74HC573PW,118 Nexperia D-type transparent latch
The 74HC573PW,118, a high-speed octal D-type transparent latch with 3-state outputs from Nexperia, is housed in a compact 20-pin TSSOP surface-mount package, designed to interface between microprocessors and peripheral devices by providing data storage and bus driving capability in digital systems. This latch features eight transparent D-type latches with a common latch enable (LE) input and a common output enable (OE) input, allowing data to be latched when LE is high and transferred to the outputs when OE is low, with outputs placed in a high-impedance state when OE is high for bus-oriented applications. The D-type latch supports bidirectional data flow when used with external pull-up resistors, features CMOS input levels with high noise immunity, and consumes low power with a typical quiescent current of 4 µA, making it suitable for battery-powered applications. It is widely deployed in microprocessor systems, memory address latches, I/O port expansion, LED drivers and data bus interfacing that require reliable, high-speed latching and 3-state bus driving.
Alternative D-type latch models
1. SN74HC573N (TI): An octal transparent D-type latch with 3-state outputs in DIP-20 package, offering similar 2V to 6V operation and 13 ns propagation delay for legacy through-hole designs.
2. MC74HC573AN (onsemi): An octal D-type latch with 3-state outputs in DIP-20 package, featuring high noise immunity and 6V operation for industrial control systems.
3. CD74HC573E (TI): An octal transparent latch with 3-state outputs in PDIP-20 package, designed for bus interface applications in commercial and industrial environments.
