Manufacturer Part Number
sn74ls195d
Description
Universal 4-bit Shift Register
Manufacturer
Freescale Semiconductor, Inc
Datasheet
UNIVERSAL 4-BIT
SHIFT REGISTER
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.
NOTES:
a. 1 TTL Unit Load (U.L.) = 40 A HIGH/1.6 mA LOW.
b. The Output LOW drive factor is 2.5 U.L. for Military (54) and 5 U.L. for Commercial (74)
