74HC374

Octal D-Type Positive Edge-Triggered

Flip-Flop with 3-State Outputs

GENERAL DESCRIPTION

FEATURES

The 74HC374 is an 8-bit D-type positive edge-triggered

flip-flop with 3-state outputs that is designed for 2.0V to

5.5V V_CCoperation.

● Wide Operating Voltage Range: 2.0V to 5.5V

● +7.8mA/-7.8mA Output Current

● CMOS Low Power Consumption

● Support Octal Bus Interface

The device is provided with a clock (CP) input and an

● 3-State Non-Inverting Outputs

��

output enable (OE) input. When data at the Dn input

● 8-Bit Positive Edge-Triggered Register

● 3-State Buffer and Independent Register

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOIC-20 and TSSOP-20

Packages

suffices for setup and hold time purposes, data can be

moved to the Qn output on the low-to-high clock

��

transition. When OE is high, all outputs are in

��

high-impedance state. OE has no influence on the state

of the flip-flops.

The clamp diodes of inputs allow the use of current

limiting resistors to connect inputs to the voltage

exceeding supply voltage.
