74HC373

Octal D-Type Transparent

Latch with 3-State Outputs

GENERAL DESCRIPTION

FEATURES

The 74HC373 is an 8-bit D-type transparent latch with

3-state outputs that is designed for 2.0V to 5.5V V_CC

operation.

● Wide Operating Voltage Range: 2.0V to 5.5V

● +7.8mA/-7.8mA Output Current

● CMOS Low Power Consumption

● 3-State Non-Inverting Outputs Suitable for

Bus-Oriented Applications

The device is provided with a latch enable (LE) input

��

and an output enable (OE) input. When LE is set high,

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOIC-20 and TSSOP-20

Packages

data at the inputs gets access to the latches and the

latches are transparent, the latch outputs will vary with

corresponding data inputs. When LE is set low, the

latches store data that appeared on the inputs for a

setup time before the high-to-low transition of LE. When

OE is high, all outputs are in high-impedance state. OE

has no influence on the state of the latches.

The clamp diodes of inputs allow the use of current

limiting resistors to connect inputs to the voltage

exceeding supply voltage.

The 74HC373 is available in Green SOIC-20 and

TSSOP-20 packages. It operates over an ambient

temperature range of -40℃ to +125℃.

H = High voltage level.

h = High voltage level one setup time before the high-to-low

transition of LE.

L = Low voltage level.
