The TC74VHC540/TC74VHC541 are advanced high speed
CMOS OCTAL BUS BUFFERs fabricated with silicon gate
C2MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The TC74VHC540 is an inverting type, and the TC74VHC541
is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in
the high-impedance state.
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: tpd = 3.7 ns (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 = 1.2 V (max)
• Pin and function compatible with 74ALS540/541

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)
