MC74LVX125
Quad Bus Buffer
With 5 V−Tolerant Inputs
The MC74LVX125 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 MC74LVX125 requires the 3−state control input (OE
) to be set
High to place the output into the high impedance state.
Features
• High Speed: t
PD
= 4.4 ns (Typ) at V

= 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

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

) or LOW−to−HIGH (t
OSLH
); parameter
guaranteed by design.
