74LVC374A

Octal D-type flip-flop; 5 V tolerant inputs/outputs;

positive-edge trigger; 3-state

Rev. 5 — 27 August 2021

Product data sheet

1. General description

The 74LVC374A is an octal positive-edge triggered D-type flip-flop with 3-state outputs. The

device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of

their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH

clock (CP) transition. 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 flip-flops. Inputs can be driven from either

3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and

5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

•

Wide supply voltage range from 1.2 V to 3.6 V

•

Overvoltage tolerant inputs to 5.5 V

CMOS low power dissipation

Direct interface with TTL levels

I_OFFcircuitry provides partial Power-down mode operation

8-bit positive edge-triggered register

Independent register and 3-state buffer operation

Complies with JEDEC standard:

•

JESD8-7A (1.65 V to 1.95 V)

JESD8-5A (2.3 V to 2.7 V)

JESD8-C/JESD36 (2.7 V to 3.6 V)

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-B exceeds 200 V

CDM JESD22-C101E exceeds 1000 V

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

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

internal review and subject to formal approval, which may result in

modifications or additions. Nexperia does not give any representations or

warranties as to the accuracy or completeness of information included herein

and shall have no liability for the consequences of use of such information.

Short data sheet — A short data sheet is an extract from a full data sheet
