74LV244

Octal buffer/line driver; 3-state

Rev. 4 — 1 March 2016

Product data sheet

1. General description

The 74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible

with 74HC244 and 74HCT244.

The 74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The output

enable inputs 1OE and 2OE control the 3-state outputs. A HIGH on nOE causes the

outputs to assume a high impedance OFF-state. The 74LV244 is identical to the 74LV240

but has non-inverting outputs.

2. Features and benefits



Wide operating voltage: 1.0 V to 5.5 V

Optimized for low voltage applications: 1.0 V to 3.6 V

Accepts TTL input levels between V

= 2.7 V and V

= 3.6 V

Typical V

OLP

(output ground bounce) < 0.8 V at V

= 3.3 V; T

amb

= 25

C

Typical V

OHV

(output V

undershoot) > 2 V at V

= 3.3 V; T

amb

= 25

C

Complies with JEDEC standard no. 7A

Multiple package options

ESD protection:



HBM JESD22-A114F exceeds 2000 V



MM JESD22-A115-A exceeds 200 V
