HCTL-2001 / 2017 / 2021
Differences between the HCTL-2001 / 2017 / 2021 and HCTL-2000 / 2016 / 2020
Application Note 5263
2. DC Characteristics
a. HCTL-2001/2017/2021
i. Quiescent supply current maximum of 100 mA ii. Output capacitance of 5 pF b. HCTL-2000/2016/2020
i. Quiescent supply current maximum of 5 mA ii. Output capacitance of 6 pF 3. AC Characteristics
a. HCTL-2001/2017/2021
i. Hold time t DSD and t DOD minimum of 10 ns b. HCTL-2000/2016/2020
i. Holt time t DSD and t DOD minimum of 5 ns 4. Output Enable (OE#) and Inhibit Logic
a. HCTL-2001/2017/2021
i. OE# must be remained low for the entire two-byte reads b. HCTL-2000/2016/2020
i. OE# can be toggled in between read operations
The HCTL-2000/2016/2020 is motion control decoder/counter that was designed many years ago on a 0.8 m m process. Due to a lack of support of the old wafer fabri-cation process, new parts have been designed using a new 0.5 m m process with higher performance, namely the HCTL-2001/2017/2021.
The HCTL-2001/2017/2021 are functionality backward compatible with the HCTL-2000/2016/2020 and pin-to-pin compatible. Since the devices are designed with add-ed features and higher performance that are also used in the HCTL-2032/2022, there are a few differences that the user should be aware when replacing the old HCTL-2000/2016/2020 with the new HCTL-2001/2017/2021. There are four differences between the old and new devices:
1. Absolute Maximum Ratings
a. HCTL-2001/2017/2021
i. DC supply voltage up to 6.0 V ii. Storage temperature up to 150° C b. HCTL-2000/2016/2020
i. DC supply voltage up to 5.5 V ii. Storage temperature up to 125° C
