8-Bit Shift Registers
These 8-bit shift registers are compatible with most other TTL and MSI logic families. All inputs are
buffered to lower the drive requirements to one normalized Series 54/74 load, and input clamping
diodes minimize switching transients to simplify system design. Maximum input clock frequency is
typically 35 megahertz and power dissipation is typically 360 mW.
