MC74LVX126
Quad Bus Buffer
With 5V−Tolerant Inputs
The MC74LVX126 is an advanced high speed CMOS quad bus
buffer. The inputs tolerate voltages up to 7.0 V, allowing the interface
of 5.0 V systems to 3.0 V systems.
The MC74LVX126 requires the 3−state control input (OE) to be set
Low to place the output into the high impedance state.
Features
• High Speed: t
PD
= 4.4 ns (Typ) at V
CC
= 3.3 V
• Low Power Dissipation: I
CC
= 4 mA (Max) at T
A
= 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: V
OLP
= 0.5 V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300 mA
• ESD Performance: Human Body Model >2000 V
Machine Model >200 V

1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGH−to−LOW (t

OSLH
); parameter
