SL74HCT373
Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate CMOS
The SL74HCT373 may be used as a level converter for interfacing
TTL or NMOS outputs to High-Speed CMOS inputs.
The SL74HCT373 is identical in pinout to the LS/ALS373.
The eight latches of the SL74HCT373 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 becomes 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-Compatible 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
