Quad Bus Buffer
The TC74VHCT125A/126A are high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent Bipolar Shottky TTL while maintaining the CMOS low power dissipation.
The TC74VHCT125A requires the 3-state control input G to be set high to place the output into the high impedance state, whereas the TC74VHCT126A requires the control input G to be set low to place the output into high impedance.
The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system.
Features
• High speed: tpd = 3.8 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
• Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
• Power down protection is provided on all inputs and outputs.
• Balanced propagation delays: tpLH ∼ − tpHL
• Low noise: VOLP = 0.8 V (max)
• Pin and function compatible with the 74 series
(74AC/HC/F/ALS/LS etc.) 125/126 types.
