DESCRIPTION

The 74LVC244A/74LVCH244A is a high performance,

low-power, low-voltage, Si-gate CMOS device, superior to

most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 or 5 V devices. In

3-state operation, outputs can handle 5 V. These features

allow the use of these devices as translators in a mixed

3.3 and 5 V environment.

The 74LVC244A/74LVCH244A is an octal non-inverting

buffer/line driver with 3-state outputs. The 3-state outputs

are controlled by the output enable inputs 1OE and 2OE.

A HIGH on nOE causes the outputs to assume a

high-impedance OFF-state. Schmitt-trigger action at all

inputs makes the circuit highly tolerant for slower input rise

and fall times.

The 244 is functionally identical to the 240, but the 240 has

inverting outputs.

QUICK REFERENCE DATA

GND = 0 V; Tamb =25 °C; tr =tf ≤ 2.5 ns.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts;

N = total load switching outputs;

Σ(CL × VCC2 × fo) = sum of the outputs.

2. The condition is VI = GND to VCC.
