74VHC125 Quad Buffer with 3-STATE Outputs
Features
■ High Speed: tPD = 3.8ns (Typ.) at VCC = 5V ■ Lower power dissipation: ICC = 4 µA (Max.) at
tm
General Description
The VHC125 contains four independent non-inverting buffers with 3-STATE outputs. It is an advanced highspeed CMOS device fabricated with silicon gate CMOS technology and achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (Min.) ■ Power down protection is provided on all inputs ■ Low noise: VOLP = 0.8V (Max.) ■ Pin and function compatible with 74HC125

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

Notes: 4. Parameter guaranteed by design. tOSLH = |tPLHmax – tPLHmin|; tOSHL = |tPHLmax – tPHLmin|. 5. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (Opr.) = CPD • VCC • fIN + ICC / 4 (per bit).
