SN74ABT573ADW

The SN74ABT573ADW is a D-Type Transparent Latch manufactured by Texas Instruments. It contains one independent circuit with an 8:8 configuration, meaning eight inputs and eight outputs. The outputs are tri-state, allowing for high-impedance states when disabled. The device operates over a supply voltage range of 4.5V to 5.5V, making it suitable for standard 5V logic systems. The maximum output current is specified as 32mA per output and 64mA total, providing sufficient drive capability for typical bus-oriented applications.

The latch is packaged in a 20-pin SOIC (small outline integrated circuit) package, which is surface-mountable and suitable for automated assembly. This logic device is commonly used in data storage, address latching, and bus interface applications where transparent latching with tri-state outputs is required. The design ensures low power consumption and high speed, characteristic of the ABT family.

For design engineers, the SN74ABT573ADW offers reliable performance within its specified voltage and current limits. The tri-state outputs facilitate shared bus architectures, and the transparent latch function allows data to pass through when enabled. The device is compatible with TTL and CMOS logic levels, providing flexibility in mixed-voltage systems.
