TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC9151P/FK 9-Bit Schmitt Buffer
TC74VHC9152P/FK 9-Bit Schmitt Inverter
The TC74VHC9151/9152 are an ultra-high-speed 9-bit Schmitt
Buffer / Inverter fabricated using silicon-gate CMOS technology.
The TC74VHC9151/9152 combines low power consumption of
CMOS with Schottky TTL speeds.
TC74VHC9151 output is a non-inverting type and the
TC74VHC9152 output is an inverting type.
All the inputs have hysteresis between the positive-going and
negative-going thresholds. Thus the TC74VHC9151/9152 are
capable of squaring up transitions of slowly changing input
signals and provides an improved noise immunity.
Additionally, all the inputs have a newly developed protection
circuit without a diode returned to VCC. This enables the inputs
to be tolerant of up to 5 volts even when power supply is down.
The input power-down protection capability makes the
TC74VHC9151/9152 ideal for a wide range of applications, such
as interfacing between different voltages, voltage translation
from 5 V to 3 V and battery back-up circuits.
High speed: tpd = 3.6 ns (typ.) (VCC = 5 V)
Low supply current: ICC = 4 A (max) (Ta = 25°C)
All inputs are provided with power-down protection.
Symmetrical rise and fall delays: tpLH ≈ tpHL
Wide operating voltage range: VCC (opr) = 2 to 5.5 V
