Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74VHC164
8-Bit Serial-In, Parallel-Out Shift Register
Features
General Description
■ High Speed: fMAX = 175MHz at VCC = 5V
■ Low power dissipation: ICC = 4µA (max.) at TA = 25°C
The VHC164 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It
achieves the high-speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation. The VHC164 is a high-speed 8-Bit
Serial-In/Parallel-Out Shift Register. Serial data is
entered through a 2-input AND gate synchronous with
the LOW-to-HIGH transition of the clock. The device features an asynchronous Master Reset which clears the
register, setting all outputs LOW independent of the
clock. An input protection circuit insures that 0V to 7V
can be applied to the input pins without regard to the
supply voltage. This device can be used to interface 5V
to 3V systems and two supply systems such as battery
backup. This circuit prevents device destruction due to
mismatched supply and input voltages.
■ High noise immunity: VNIH = VNIL = 28% VCC (min.)
■ Power down protection provided on all inputs
■ Low noise: VOLP = 0.8V (max.)
■ Pin and function compatible with 74HC164

Functional Description
X = Immaterial
The VHC164 is an edge-triggered 8-bit shift register with
serial data entry and an output from each of the eight
stages. Data is entered serially through one of two inputs
(A or B); either of these inputs can be used as an active
High Enable for data entry through the other input. An
unused input must be tied HIGH.
Q = Lower case letters indicate the state of the
referenced input or output one setup time prior to
the LOW-to-HIGH clock transition.
Each LOW-to-HIGH transition on the Clock (CP) input
shifts data one place to the right and enters into Q0 the
logical AND of the two data inputs (A • B) that existed
before the rising clock edge. A LOW level on the Master
Reset (MR) input overrides all other inputs and clears
the register asynchronously, forcing all Q outputs LOW.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
