74LV244PW

Octal buffer/line driver (3-state)

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.

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
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
