8-Bit Shift Register/Latch (3-state)
The TC74VHC595 is an advanced high speed 8-BIT SHIFT
REGISTER/LATCH fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation.
The TC74VHC595 contains an 8-bit static shift register which
feeds an 8-bit storage register.
Shift operation is accomplished on the positive going transition of
the SCK input. The output register is loaded with the contents of
the shift register on the positive going transition of the RCK input.
Since RCK and SCK signal are independent, parallel outputs can be
held stable during the shift operation. And, since the parallel
outputs are 3-state, it can be directly connected to 8-bit bus. This
register can be used in serial-to-parallel conversion, data receivers,
etc.
An input protection circuit ensures that 0 to 5.5 V can be applied
to the input pins without regard to the supply voltage. This device
can be used to interface 5 V to 3 V systems and two supply systems
such as battery back up. This circuit prevents device destruction
due to mismatched supply and input voltages.
Features
• High speed: fmax = 185 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Power down protection is provided on all inputs.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
• Low noise: VOLP = 1.0 V (max)
• Pin and function compatible with 74ALS595
Note: xxxFN (JEDEC SOP) is not available in
Japan.
