Texas Instruments SN74HC373 Octal Transparent D-Type Latches With 3-State Outputs SN74HC373PW

The SN74HC373PW is an octal transparent D-type latch with 3-state outputs, designed for driving capacitive or low-impedance loads. It operates within a voltage range of 2 V to 6 V and features high-current outputs capable of driving up to 15 LSTTL loads. The device has a low power consumption of 80 µA maximum and a typical propagation delay of 13 ns. It provides ±6 mA output drive at 5 V and a low input current of 1 µA maximum. The latches are transparent while the latch-enable (LE) input is high, allowing the Q outputs to follow the D inputs. When LE is low, the outputs are latched. This product is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers. The SN74HC373PW is packaged in a 20-pin TSSOP format, measuring 6.50 mm x 4.40 mm.
