SN54HC373 Datasheet | Texas Instruments

Features - Wide operating voltage range of 2 V to 6 V - High-current 3-state true outputs can drive up to 15 LSTTL loads - Low power consumption, 80-µA max ICC - Typical tpd = 13 ns - ±6-m A output drive at 5 V - Low input current of 1 µA max - Eight high-current latches in a single package - Full parallel access for loading 2 Description These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight latches of the ’HC373 devices are transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.
