MC74VHCT125A D

MC74VHCT125A
Quad Bus Buffer
with 3−State Control Inputs
The MC74VHCT125A 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 MC74VHCT125A requires the 3−state control input (OE) to be
set High to place the output into the high impedance state.
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3 V to 5.0 V, because it
has full 5.0 V CMOS level output swings.
The VHCT125A input structures provide protection when voltages
between 0 V and 5.5 V are applied, regardless of the supply voltage.
The output structures also provide protection when VCC = 0 V. These
input and output structures help prevent device destruction caused by
supply voltage − input/output voltage mismatch, battery backup, hot
insertion, etc.
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 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V CC ).
Unused outputs must be left open.
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of
these limits are exceeded, device functionality should not be assumed, damage may occur and
reliability may be affected.

1. Parameter guaranteed by design. tOSLH = |tPLHm − tPLHn|, tOSHL = |tPHLm − tPHLn|.
2. 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 buffer). CPD is used to determine the
no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
