Description

The 74AHC573D belongs to 74AHC/AHCT573 family which are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). The 74AHC/AHCT573 are octal D-type transparent latches featuring separate D-type inputs for each latch and 3-state outputs for bus oriented applications. They are specified in compliance with JEDEC standard No. 7A. A Latch Enable (LE) input and an Output Enable (OE) input are common to all latches. When LE is LOW the latches store the information that was present at the D-inputs a set-up time preceding the HIGH-to-LOW transition of LE. When OE is LOW, the contents of the 8 latches are available at the outputs. When OE is HIGH, the outputs of the 74AHC573D go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. The '573' consists of eight D-type transparent latches with 3-state true outputs. When LE is HIGH, data at the Dn inputs enters the latches. In this condition the latches are transparent, i.e. a latch output will change state each time its corresponding D-input changes. The '573' is functionally identical to the '533', '563' and '373', but the '533' and '563' have inverted outputs and the '563' and '373' have a different pin arrangement.

The features of 74AHC573D can be summarized as (1)ESD protection: HBM EIA/JESD22-A114-A, exceeds 2000 V, MM EIA/JESD22-A115-A, exceeds 200 V, CDM EIA/JESD22-C101, exceeds 1000 V; (2)balanced propagation delays; (3)all inputs have schmitt-trigger actions; (4)common 3-state output enable input; (5)functionally identical to the '563' and '373'; (6)inputs accepts voltages higher than VCC; (7)for AHC only: operates with CMOS input levels; (8)for AHCT only: operates with TTL input levels; (9)specified from -40 to +85 and +125 °C.
