TC74HC597AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC597AP,TC74HC597AF
8-Bit Latch/Shift Register
The TC74HC597A is a high speed CMOS 8-BIT
PARALLEL-IN/SERIAL-IN SERIAL-OUT LATCH/SHIFT
REGISTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
It consists of an 8-bit data register feeding an 8-bit shift
register. The parallel data on the A to H inputs is stored in the
input register on the positive going transition of RCK.
When the SLOAD input is held low, the input register data is
passed into the shift registers. When SLOAD input is held high,
www.DataSthheeeste4riUal.cdoamta input (SI) is enabled and the eight flip-flops
perform serial shifting on the positive transition of SCK.
A direct clear input ( SCLR ) sets the 8-bit shift register to zero.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: fmax = 60 MHz (typ.) at VCC = 5 V
Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC
Output drive capability: 10 LSTTL loads
Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 6 V
Pin and function compatible with 74LS597

www.DataSheet4U.coUmsing continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).

applied until 300 mW.
