SN74HCT373

SN54HCT373, SN74HCT373 SCLS009G – MARCH 1984 – REVISED JULY 2022 SNx4HCT373 Octal Transparent D-Type Latches With 3-State Outputs 1 Features Operating voltage range of 4.5 V to 5.5 V High-current 3-state true outputs can drive up to 15 LSTTL loads Low power consumption, 80-μA max ICC Typical tpd =21 ns ±6-mA output drive at 5 V Low input current of 1 μA max Inputs are TTL-voltage compatible 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 ’HCT373 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.
