74LVC16244A; 74LVCH16244A

16-bit buffer/line driver; 5 V input/output tolerant; 3-state

The 74LVC16244A; 74LVCH16244A are 16-bit non-inverting buffer/line drivers with 3-state bus compatible outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. It features four output enable inputs, (1OE to 4OE) each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications.

The 74LVCH16244A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs.

Features and benefits

  • 5 V tolerant inputs/outputs for interfacing with 5 V logic
  • Wide supply voltage range from 1.2 V to 3.6 V
  • CMOS low power consumption
  • Multibyte flow-through standard pin-out architecture
  • Low inductance multiple power and ground pins for minimum noise and ground bounce
  • Direct interface with TTL levels
  • High-impedance when VCC = 0 V
  • All data inputs have bus hold. (74LVCH16244A only)
  • Complies with JEDEC standard:
    • JESD8-7A (1.65 V to 1.95 V)
    • JESD8-5A (2.3 V to 2.7 V)
    • JESD8-C/JESD36 (2.7 V to 3.6 V)
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-B exceeds 200 V
    • CDM ANSI/ESDA/Jedec JS-002 exceeds 1000 V
  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
