TC74AC126P/F Quad Bus Buffer
The TC74AC125/126 are advanced high speed CMOS QUAD
BUS BUFFERs fabricated with silicon gate and double-layer
metal wiring C²MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The TC74AC125 requires the 3-state control input G to be set
high to place the output into the high impedance state, whereas
the TC74AC126 requires the control input to be set low to place
the output into high impedance.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: t_pd = 4.0 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 8 μA (max) at Ta = 25°C
• High noise immunity: V_NIH = V_NIL = 28% V_CC (min)
• Symmetrical output impedance: |I_OH| = I_OL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Wide operating voltage range: V_{CC (opr)} = 2 to 5.5 V
• Pin and function compatible with 74F125/126
