MM74HC594 8-Bit Shift Register
with Output Registers
General Description
This high speed shift register utilizes advanced silicon-gate
CMOS technology This device possesses the high noise
immunity and low power consumption of standard CMOS
integrated circuits as well as the ability to drive 15 LS-TTL
loads
This device contains an 8-bit serial-in parallel-out shift reg-
ister that feeds an 8-bit D-type storage register Separate
clocks and direct overriding clears are provided for both the
shift register and the storage register The shift register has
a direct-overriding clear serial input and serial output (stan-
dard) pins for cascading Both the shift register and storage
register use positive-edge triggered clocks If both clocks
are connected together the shift register state will always
be one clock pulse ahead of the storage register
The 54HC 74HC logic family is speed function and pin-out
compatible with the standard 54LS 74LS logic family All
inputs are protected from damage due to static discharge by
internal diode clamps to VCC and ground
