CY74FCT373T (ACTIVE) Octal Transparent D-Type Latches with 3-State Outputs

Octal Transparent D-Type Latches with 3-State Outputs - CY74FCT373T
Datasheet
8-Bit Latches datasheet (Rev. B)
 

Description

The \x92FCT373T devices consist of eight latches with 3-state outputs for bus-organized applications. When the latch-enable (LE) input is high, the flip-flops appear transparent to the data. Data that meets the required setup times are latched when LE transitions from high to low. Data appears on the bus when the output-enable (OE\) input is low. When OE\ is high, the bus output is in the high-impedance state. In this mode, data can be entered into the latches.

These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
