74HC166; 74HCT166

8-bit parallel-in/serial out shift register

Rev. 5 — 9 August 2021

Product data sheet

1. General description

The 74HC166; 74HCT166 is an 8-bit serial or parallel-in/serial-out shift register. The device

features a serial data input (DS), eight parallel data inputs (D0 to D7) and a serial output (Q7).

When the parallel enable input (PE) is LOW, the data from D0 to D7 is loaded into the shift register

on the next LOW-to-HIGH transition of the clock input (CP). When PE is HIGH, data enters the

register serially at DS with each LOW-to-HIGH transition of CP. When the clock enable input (CE)

is LOW data is shifted on the LOW-to-HIGH transitions of CP. A HIGH on CE disables the CP input.

Inputs include clamp diodes which enable the use of current limiting resistors to interface inputs to

voltages in excess of V_CC

.

Nexperia does not accept any liability related to any default, damage, costs

or problem which is based on any weakness or default in the customer’s

applications or products, or the application or use by customer’s third party

customer(s). Customer is responsible for doing all necessary testing for the

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.

Draft — The document is a draft version only. The content is still under

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

with the same product type number(s) and title. A short data sheet is

intended for quick reference only and should not be relied upon to contain

product for such automotive applications, use and specifications, and (b)

whenever customer uses the product for automotive applications beyond

Nexperia’s specifications such use shall be solely at customer’s own risk,

and (c) customer fully indemnifies Nexperia for any liability, damages or failed

product claims resulting from customer design and use of the product for

automotive applications beyond Nexperia’s standard warranty and Nexperia’s

product specifications.
