Quad Bus Buffer
with 3-State Control Inputs
The MC74VHC125 is a high speed CMOS quad bus buffer fabricated with
silicon gate CMOS technology. It achieves high speed operation similar to
equivalent Bipolar Schottky TTL while maintaining CMOS low power
dissipation.
The MC74VHC125 requires the 3–state control input (OE) to be set High
to place the output into the high impedance state.
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 7V, allowing the interface of 5V systems to 3V systems.
High Speed: tPD = 3.8ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4A (Max) at TA = 25°C
High Noise Immunity: VNIH = VNIL = 28% VCC
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2V to 5.5V Operating Range
Low Noise: VOLP = 0.8V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 72 FETs or 18 Equivalent Gates
