1998 May 20

853-1876 19419

FEATURES

• 5-volt tolerant inputs/outputs, for interfacing with 5-volt logic

• Supply voltage range of 2.7V to 3.6V

• Complies with JEDEC standard no. 8-1A

• CMOS low power consumption

• Direct interface with TTL levels

• High impedance when V

CC = 0V

• Bushold on all data inputs (74LVCH244A only)

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 3.3V or 5V devices. In 3-State

operation, outputs can handle 5V. These features allow the use of

these devices as translators in a mixed 3.3V/5V 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

non-inverting outputs.

NOTE:

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

PD = CPD x VCC2 x fi + S (CL x VCC2 x fo) where:

fi = input frequency in MHz; CL = output load capacity in pF;

fo = output frequency in MHz; VCC = supply voltage in V;

S (CL x VCC2 x fo) = sum of outputs.

2. The condition is VI = GND to VCC
