SN74LS164

Serial-In Parallel-Out

Shift Register

The SN74LS164 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. It utilizes

the Schottky diode clamped process to achieve high speeds and is fully

compatible with all ON Semiconductor TTL products.

• Typical Shift Frequency of 35 MHz

• Asynchronous Master Reset

• Gated Serial Data Input

• Fully Synchronous Data Transfers

• Input Clamp Diodes Limit High Speed Termination Effects

• ESD > 3500 Volts
