General description
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 =0V
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 JESD22-C101E exceeds 1000 V
Specified from
