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 VCC = 2.7 V and VCC = 3.6 V
Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V; Tamb = 25 C
Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V; Tamb = 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
