MC74VHC126
Quad Bus Buffer
with 3--State Control Inputs
The MC74VHC126 is a high speed CMOS quad bus buffer
fabricated with silicon gate CMOS technology. It achieves
noninverting high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining CMOS low power dissipation.
The MC74VHC126 requires the 3--state control input (OE) to be set
Low to place the output into high impedance.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
• High Speed: tPD = 3.8 ns (Typ) at VCC = 5.0 V
• Low Power Dissipation: ICC = 4.0 μA (Max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 28% VCC
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Designed for 2.0 V to 5.5 V Operating Range
• Low Noise: VOLP = 0.8 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance: HBM > 2000 V; Machine Model > 200 V
• Chip Complexity: 72 FETs or 18 Equivalent Gates
• These devices are available in Pb--free package(s). Specifications herein
apply to both standard and Pb--free devices. Please see our website at
