Octal Universal Schmitt Buffer with 3-State Outputs
The TC74VHC9541 is an ultra-high-speed octal Schmitt buffer
fabricated using silicon-gate CMOS technology. The
TC74VHC9541 combines low power consumption of CMOS with
Schottky TTL speeds.
The outputs can be put in the high-impedance state by placing
a logic HIGH on the Enable ( G ) input. The CONT input
determines the logical inversion of data. A logic LOW on the
CONT input configures the TC74VHC9541 as an inverter; a logic
HIGH on the CONT input configures the TC74VHC9541 as a
buffer.
All the inputs have hysteresis between the positive-going and
negative-going thresholds. Thus the TC74VHC9541 is 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
TC74VHC9541 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.
Features
• High speed: tpd = 5.0 ns (typ.) (VCC = 5 V)
• Low supply current: ICC = 4 μA (max) (Ta = 25°C)
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• 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
• Pin-compatible with TC74VHC540 and TC74VHC541

Note 1: Parameter guaranteed by design.
tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn|
Note 2: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC / 8 (per bit)
