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,
the serial data 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: f_max = 60 MHz (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |I_OH| = I_OL = 4 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2 to 6 V
• Pin and function compatible with 74LS597
