The TC74HC540A/TC74HC541A are high speed CMOS OCTAL
BUS BUFFERs fabricated with silicon gate C²MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC540A is an inverting type, and the TC74HC541A
is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in
the high-impedance state.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: t_pd = 10 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Output Drive Capability: 15 LSTTL loads
• Symmetrical output impedance: |I_OH| = I_OL = 6 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_CC (opr) = 2 to 6 V
• Pin and function compatible with 74LS540/541
