MC74HC20A
Dual 4-Input NAND Gate
High−Performance Silicon−Gate CMOS
The MC74HC20A is identical in pinout to the LS20. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
Features
• Output Drive Capability: 10 LSTTL Loads • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2 V to 6 V • Low Input Current: 1 mA • High Noise Immunity Characteristic of CMOS Devices • These are Pb−Free Devices • NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
