SN54/74LS195A

UNIVERSAL 4-BIT

SHIFT REGISTER

The SN54/74LS195A is a high speed 4-Bit Shift Register offering typical

shift frequencies of 39 MHz. It is useful for a wide variety of register and

counting applications. It utilizes the Schottky diode clamped process to

achieve high speeds and is fully compatible with all Motorola TTL products.
