74LVC1G14单芯片阈值稳定器反转器数据表说明书

74LVC1G14Single Schmitt-trigger inverterRev. 15 — 8 June 2018Product data sheet1General descriptionThe 74LVC1G14 provides the inverting buffer function with Schmitt-trigger input. It iscapable of transforming slowly changing input signals into sharply defined, jitter-freeoutput signals.The input can be driven from either 3.3 V or 5 V devices. This feature allows the useof this device in a mixed 3.3 V and 5 V environment. Schmitt-trigger action at the inputmakes the circuit tolerant for slower input rise and fall time.This device is fully specified for partial power-down applications using I OFF. The I OFFcircuitry disables the output, preventing the damaging backflow current through thedevice when it is powered down.2Features and benefits•Wide supply voltage range from 1.65 V to 5.5 V•High noise immunity•Complies with JEDEC standard:–JESD8-7 (1.65 V to 1.95 V)–JESD8-5 (2.3 V to 2.7 V)–JESD8-B/JESD36 (2.7 V to 3.6 V).•±24 mA output drive (V CC = 3.0 V)•CMOS low power consumption•Latch-up performance exceeds 250 mA•Direct interface with TTL levels•Unlimited rise and fall times•Input accepts voltages up to 5 V•Multiple package options•ESD protection:–HBM: ANSI/ESDA/JEDEC JS-001 Class 2 exceeds 2000 V–MM: JESD22-A115-A exceeds 200 V.•Specified from -40 °C to +85 °C and -40 °C to +125 °C.3Applications•Wave and pulse shaper•Astable multivibrator•Monostable multivibratorSingle Schmitt-trigger inverter 4Ordering information5Marking[1]The pin 1 indicator is located on the lower left corner of the device, below the marking code.Single Schmitt-trigger inverter6Functional diagram7Pinning information7.1Pinning74LVC1G14n.c.V CCA GNDY001aab65512354Figure 4.

HD74ALVC16283418-bit Universal Bus Driver with 3-state Outputsand Inverted Latch EnableADE-205-217D (Z)5th. EditionDecember 1999 DescriptionThe HD74ALVC162834 is an 18-bit universal bus driver designed for 2.3 V to 3.6 V Voperation.CCData flow from A to Y is controlled by the output enable (OE). The device operates in the transparent mode when the latch enable (LE) is low. When LE is low, the A data is latched if the clock (CLK) input is held at a high or low logic level. If the LE is high, the A data is stored in the latch/flip flop on the low to high transition of CLK. When OE is high, the outputs are in the high impedance state.To ensure the high impedance state during power up or power down, OE should be tied to Vthrough aCCpullup registor; the minimum value of the registor is determined by the current sinking capability of the driver.All outputs, which are designed to sink up to 12 mA, include 26 Ω resistors to reduce overshoot and undershoot.Features• Meets “PC SDRAM registered DIMM design support document, Rev. 1.2”• V CC = 2.3 V to 3.6 V• Typical V OL ground bounce < 0.8 V (@V CC = 3.3 V, Ta = 25°C)• Typical V OH undershoot > 2.0 V (@V CC = 3.3 V, Ta = 25°C)• High output current ±12 mA (@V CC = 3.0 V)• All outputs have equivalent 26 Ω series resistors, so no external resistors are requiredHD74ALVC1628342Function TableInputs OE LE CLK A Output Y H X X X Z L L X L L L L X H H L H ↑L L L H ↑H H L HL or HXY 0 *1H :High level L :Low level X :ImmaterialZ :High impedance↑ :Low to high transitionNote:1.Output level before the indicated steady-state input conditions were established.HD74ALVC162834 Pin Arrangement3HD74ALVC1628344Absolute Maximum RatingsItemSymbol Ratings Unit ConditionsSupply voltage range V CC –0.5 to 4.6V Input voltage range *1V I –0.5 to 4.6V Output voltage range *1, 2V O –0.5 to V CC +0.5V Input clamp current I IK –50mA V I < 0Output clamp current I OK ±50mA V O < 0 or V O > V CC Continuous output current I O±50mA V O = 0 to V CC V CC , GND current / pin I CC or I GND ±100mA Maximum power dissipation at Ta = 55°C (in still air) *3P T 1W TSSOP Storage temperature rangeTstg–65 to 150°CStresses beyond those listed under “absolute maximum ratings” may cause permanent damage to thedevice.

This device can be used to interface 5V to 3V.Pin configuration and function are the same as those of the 74VHC04 but the 74VHC14 has hysteresis.This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals.All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.74VHC14HEX SCHMITT INVERTERFigure 1: Pin Connection And IEC Logic SymbolsTable 1: Order CodesPACKAGE T & R SOP 74VHC14MTR TSSOP74VHC14TTR74VHC142/11Figure 2: Input Equivalent CircuitTable 2: Pin DescriptionTable 3: Truth TableTable 4: Absolute Maximum RatingsAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
