TC7MH541FK Non-Inverted, 3-State Outputs
The TC7MH540FK and TC7MH541FK 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 TC7MH540FK is an inverting type, and the TC7MH541FK
is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in the
high-impedance state.
Weight: 0.03 g (typ.)
An input protection circuit ensures that 0 to 7 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.) (VCC = 5 V)
• Low power dissipation: ICC = 4 µA (max) (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) = 2~5.5 V
• Low noise: VOLP = 1.0 V (max)
• Pin and function compatible with 74ALS540/541
