TC7MH165FK
8-Bit Shift Register (P-In, S-Out)
The TC7MH165FK is an advanced high speed CMOS 8-bit
parallel/serial-in, serial-out shift register 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.
It consists of parallel-in or serial-in, serial-out 8-bit shift
register with a gated clock input. When the SHIFT/LOAD input
is held high, the serial data input is enabled and the eight
flip-flops perform serial shifting with each clock pulse.
When the SHIFT/ LOAD input is held low, the parallel data is
loaded synchronously into the register at positive going transition
of the clock pulse.
Weight: 0.02 g (typ.)
The CK-INH input should be shifted high only when the CK
input is held high.
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 on two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.
Features
• High speed: f_max = 150 MHz (typ.) (V_CC = 5 V)
• Low power dissipation: I_CC = 4 μA (max) (Ta = 25°C)
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Power down protection is provided on all inputs.
• Balanced propagation delays: t_pLH ≈ t_pHL
• Wide operating voltage range: V_{CC (opr)} = 2~5.5 V
• Pin and function compatible with 74ALS165
