74HC573; 74HCT573

Octal D-type transparent latch; 3-state

Rev. 8 — 10 September 2021

Product data sheet

1. General description

The 74HC573; 74HCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device

features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs

enter the latches. In this condition the latches are transparent, a latch output will change each time

its corresponding D-input changes. When LE is LOW the latches store the information that was

present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE

causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not

affect the state of the latches. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

•

Wide supply voltage range from 2.0 to 6.0 V

•

CMOS low power dissipation

High noise immunity

Input levels:

•

For 74HC573: CMOS level

For 74HCT573: TTL level

•

Inputs and outputs on opposite sides of package allowing easy interface with microprocessors

Useful as input or output port for microprocessors and microcomputers

3-state non-inverting outputs for bus-oriented applications

Common 3-state output enable input

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Complies with JEDEC standards:

•

JESD8C (2.7 V to 3.6 V)

JESD7A (2.0 V to 6.0 V)

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Multiple package options

Specified from -40 °C to +85 °C and from -40 °C to +125 °C
