DESCRIPTION

The UTC U74AUP1T08 performs the Boolean function Y = A • B

or Y = A + B with designation for logic-level translation applications

with output referenced to supply VCC.

The UTC U74AUP1T08 technology is the industry's lowest-power

logic technology designed for use in extending battery-life in

operating. All input levels that accept 1.8V LVCMOS signals, while

operating from either a single 3.3V or 2.5V VCC supply. This product

also maintains excellent signal integrity.

The wide VCC range of 2.3V to 3.6V allows the possibility of

switching output level to connect to external controllers or

processors.

Schmitt-trigger inputs (ΔVT = 210mV between positive and

negative input transitions) offer improved noise immunity during

switching transitions, which is especially useful on analog

mixed-mode designs. Schmitt-trigger inputs reject input noise,

ensure integrity of output signals, and allow for slow input signal

transition.

Ioff is a feature that allows for powered-down conditions (VCC = 0

V) and is important in portable and mobile applications. When VCC =

0 V, signals in the range from 0V to 3.6V can be applied to the inputs

and outputs of the device. No damage occurs to the device under

these conditions.

The UTC U74AUP1T08 is designed with optimized current-drive

capability of 4mA to reduce line reflections, overshoot, and

undershoot caused by high-drive outputs.
