74HC573 - Octal D-type transparent latch DIP-IC

74HC573 Octal D-Type Transparent Latch DIP-IC

The 74HC573 is a high-speed Si-gate CMOS octal D-type transparent latch. This DIP-IC features eight D-type inputs and 3-state outputs. It is suitable for bus-oriented applications. Pin compatibility with low power Schottky TTL (LSTTL) is provided, and the device complies with JEDEC standard no. 7A. A common Latch Enable (LE) input controls data entry. An Output Enable (OE) input manages the 3-state outputs. When LE is HIGH, data passes directly to outputs; when LE is LOW, data is stored. The 3-state outputs facilitate shared data buses. This integrated circuit is used in microprocessors, microcomputers, and general-purpose digital logic.
