SNx4LVC541A Octal Buffers/Drivers With 3-State Outputs

1 Features

• Operates from 1.65V to 3.6V

• Inputs accept voltages to 5.5V

• Maximum tpd of 5.1ns at 3.3V

• Typical VOLP (output ground bounce) <0.8V at VCC

= 3.3V, TA = 25°C

• Typical VOHV (output VOH undershoot) >2V at VCC

= 3.3V, TA = 25°C

• Support mixed-mode signal operation on all ports

(5V input/output voltage with 3.3V VCC)

• Ioff supports live insertion, partial-power-down

mode, and back-drive protection

• Latch-up performance exceeds 100mA per JESD

78

• On products compliant to MIL-PRF-38535, all

parameters are tested unless otherwise noted, on

all other products, production processing does not

necessarily include testing of all parameters

2 Applications

• Drive an indicator LED

• Redrive a digital signal

• Drive a transmission line

• Hold a signal during controller reset

3 Description

The SNx4LVC541A contains eight non-inverting

buffers with 3-state outputs. The active low output

enable pins (OE1 and OE2) control all eight channels,

and are configured so that both must be low for the

outputs to be active.
