SC74HC595
8-BIT SHIFT REGISTER (SERIAL INPUT, 3S PARALLEL OUTPUT WITH
LATCHES)
DESCRIPTION
SC74HC595 utilizes advanced CMOS technology, and has
8-bit shift register with serial input, serial/parallel output and 8-
bit tri-state output flip-latch. The pin configuration is in accord
SOP-16-300-1.27 SOP-16-225-1.27
with the 54LS/74LS series, and the operating speed is similar
to 54LS/74LS. This circuit has the protecting circuit for all the
inputs and outputs to avoid the damage caused by the static
discharge. And it has the ability of driving load and features
SSOP-16-300-0.65
high noise immunity.
The register and flip-latch both have separate clock inputs
(SCK and RCK). The serial input data (IS) is stored into
register at the rising edge of SCK; the data of register is stored
into flip-latch at the rising edge of RCK. The low level of clear
DIP-16-300-2.54 TSSOP-16-225-0.65
port ( SCLR ) only reset the register, and is no effect to flip-
latch. When the control enable ( G ) is high level, the parallel-
out is level Z.

(*): CPD is defined as the internal equivalent capacitance of the IC. It is calculated from the operating current
without load; and the average operating current can be obtained by the equation: ICC (opr) =CPD*VCC*fIN+ICC.
