SN74ABT373PWR

The SN74ABT373PWR is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. This component features 8 independent circuits and operates within a voltage range of 4.5V to 5.5V. The device supports TTL-compatible CMOS input types and provides tri-state outputs. It has a maximum clock frequency of 150 MHz and a typical propagation delay of 4.6ns. The operating temperature range is from -40°C to 85°C, making it suitable for various environmental conditions. The latch is available in a 20-TSSOP package, designed for surface mounting.

Key electrical characteristics include high drive outputs with IOL of 64mA and IOH of -32mA. The supply current is a maximum of 30000µA. Features such as partial power down (Ioff) and power-up 3-state are incorporated. The technology family is ABT, known for its high speed and low power dissipation.

This D-type transparent latch is ideal for applications requiring data storage and buffering in digital systems. Its transparent nature means that while the latch-enable input is high, the outputs follow the data inputs. When the latch-enable is taken low, the outputs are latched at the logic levels present at the data inputs. The buffered output-enable input allows for placing the outputs in a normal or high-impedance state.
