Shift Register
TECHNICAL DATA
IN74ALS164
This device 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. This
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 achieved high speeds and is fully
compatible with all TTL products.
• Switching specifications at 50 pF
• Switching specifications guaranteed over full temperature and VCC
range
• Functionally and pin-for-pin compatible with Schottky and LS TTL
counterpart
