KK74HCT373A
KK74HCT373A is Octal 3-State Noninverting Transparent Latch manufactured by Kodenshi AUK Group.
TECHNICAL DATA
Octal 3-State Noninverting Transparent Latch
The KK74HCT373A may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. The KK74HCT373A is identical in pinout to the LS/ALS373. The eight latches of the KK74HCT373A are transparent D-type latches. While the Latch Enable is high the Q outputs follow the Data Inputs. When Latch Enable is taken low, data meeting the setup and hold times bees latched. The Output Enable does not affect the state of the latch, but when Output Enable is high, all outputs are forced to the high-impedance state. Thus, data may be latched even when the outputs are not enabled.
- TTL/NMOS-patible Input Levels
- Outputs Directly Interface to CMOS, NMOS, and TTL
- Operating Voltage Range: 4.5 to 5.5 V
- Low Input Current: 1.0 µA
