TC74AC166P/F/FN
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC166P,TC74AC166F,TC74AC166FN
8-Bit Shift Register (P-IN, S-OUT)
The TC74AC166 is an advanced high speed CMOS 8-BIT
PARALLEL/SERIAL-IN, SERIAL-OUT SHIFT REGISTER
fabricated with silicon gate and double-layer metal wiring
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 and an overriding clear input.
The parallel-in or serial-in modes are controlled by the
SHIFT/ LOAD input. When the SHIFT/ LOAD input is held
high, the serial data input is enabled and the eight flip-flops
perform serial shifting on each clock pulse. When held low, the
parallel data inputs are enabled and synchronous loading occurs
on the next clock pulse. Clocking is accomplished on the
low-to-high transition of the clock pulse. The CLOCK-INHIBIT
input should be shifted high only while the CLOCK input is held
high. A direct clear input overrides all other inputs, including the
clock, and sets all the flip-flops to zero. Functional details are
shown in the truth table and the timing charts.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: fmax = 170 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Pin and function compatible with 74HC166
Pin Assignment
Note: xxxFN (JEDEC SOP) is not available in
Japan.
