74CBTLV1G125
Single bus switch
Rev. 01 — 23 February 2007
Product data sheet
1. General description
The 74CBTLV1G125 is a high-performance, low-power, low-voltage, Si-gate CMOS
device, superior to most advanced CMOS compatible TTL families.
Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall
times across the entire V
CC
range from 2.3 V to 3.6 V.
This device is fully specified for partial power-down applications using I
OFF
.
The I
OFF
circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
The 74CBTLV1G125 provides a single high-speed line switch. The switch is disabled
when the output enable (OE) input is high.
To ensure the high-impedance OFF-state during power up or power down, OE should be
tied to the V
CC
through a pullup resistor. The minimum value of the resistor is determined
by the current-sinking capability of the driver.
