16-bit buffer/line driver; inverting (3-State)

Product specification

74LVC16240A

FEATURES

• 5 volt tolerant inputs/outputs for interfacing with 5V logic

• Wide supply voltage range of 1.2V to 3.6V

• Complies with JEDEC standard no. 8-1A

• CMOS low power consumption

• MULTIBYTETM flow-through standard pin-out architecture

• Low inductance multiple power and ground pins for minimum

noise and ground bounce

• Direct interface with TTL levels

DESCRIPTION

The 74LVC16240A 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 in a mixed 3.3V/5V

environment.

The 74LVC16240A is a 16-bit 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.

The 74LVC16240A is identical to the 74LVC16244A but has

inverting outputs.

NOTES:

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.
