SN74AC373

The SN74AC373 is an 8-bit octal D-type transparent latch featuring 3-state outputs, designed by Texas Instruments. This logic IC belongs to the AC technology family and is suitable for applications requiring high-speed data buffering and bus driving.

Key electrical specifications include a maximum clock frequency of 100 MHz, output current capabilities of IOL (max) 24 mA and IOH (max) -24 mA, and a low supply current of 40 µA (max). The device operates over a wide voltage range from 2V to 6V, with inputs accepting voltages up to 6V. The maximum propagation delay is 9.5 ns at 5V.

Designed for driving highly capacitive or low-impedance loads, the SN74AC373 is particularly useful for implementing buffer registers, I/O ports, and bidirectional bus drivers. It offers full parallel access for loading and features balanced, noninverting 3-state outputs that drive bus lines directly.

The operating temperature range for this component is -40°C to 85°C. It is available in various package types including SOIC, SOP, TSSOP, SSOP, and PDIP, with surface mount as the typical mounting type.
