Texas Instruments SN74ABT373 Octal Transparent D-Type Latches With 3-State Outputs SN74ABT373NSRE4

The SN74ABT373 is an octal transparent D-type latch featuring 3-state outputs, designed for high-performance applications. It operates with a supply voltage range of 4.5V to 5.5V and is characterized for temperatures from -40¬8C to 85¬8C. The device includes eight latches that follow the data inputs while the latch-enable (LE) input is high, and retains the output state when LE is low. A buffered output-enable (OE) input allows the outputs to be placed in a high-impedance state, facilitating bus driving without additional components. The SN74ABT373 supports high-drive outputs with a maximum output current of 64 mA for low states and 32 mA for high states. It is built using Texas Instruments' EPIC-II BiCMOS technology, which significantly reduces power dissipation and enhances latch-up performance, exceeding 500 mA per JEDEC standards. The device is available in multiple package options, including plastic small-outline and ceramic chip carriers, making it versatile for various applications.
