The MC74LVX125 is an advanced high speed CMOS quad bus buf fer.
The inputs tolerate voltages up to 7V , allowing the interface of 5V systems
to 3V systems.
The MC74LVX125 requires the 3–state control input (OE
) to be set
High to place the output into the high impedance state.
• High Speed: t
PD
= 4.4ns (Typ) at VCC = 3.3V
• Low Power Dissipation: I
CC
= 4µA (Max) at TA = 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: V
OLP
= 0.5V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
