KK74HC373A
KK74HC373A is Octal 3-State Noninverting manufactured by Kodenshi AUK Group.
TECHNICAL DATA
Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate CMOS
The KK74HC373A is identical in pinout to the LS/ALS373. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time bees latched. The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the highimpedance state. Thus, data may be latched even when the outputs are not enabled.
- Outputs Directly Interface to CMOS, NMOS, and TTL
- Operating Voltage Range: 2.0 to 6.0 V
- Low Input Current: 1.0 µA
- High Noise Immunity Characteristic of CMOS Devices
