DESCRIPTION
The 74LVC(H)16244A is a high-performance, low power,
low voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families. Inputs can be
driven from either 3.3 or 5 V devices. In 3-state operation,
outputs can handle 5 Volt. These features allow the use of
these devices as a mixed 3.3 and 5 V environment.
The 74LVC(H)16244A is a 16-bit non-inverting buffer/line
driver with 3-state outputs. The device can be used as four
4-bit buffers, two 8-bit buffers or one 16-bit buffer. The
device features four Output Enables (1OE, 2OE, 3OE and
4OE), each controlling four of the 3-state outputs. A HIGH
on nOE causes the outputs to assume a high-impedance
OFF-state.
The 74LVC(H)16244A is identical to the 74LVC16240A
but has non-inverting outputs.
The 74LVCH16244A bushold data inputs eliminates the
need for external pull-up resistors to hold unused inputs.

Notes
1. All typical values are measured at VCC = 3.3 V and Tamb =25°C.
2. For bushold parts, the bushold circuit is switched off when VI>V
CC allowing 5.5 V on the input pin.
3. Valid for data inputs of bushold parts (74LVCH16244A) only. For data inputs only, control inputs do not have a
bushold circuit.
4. The specified sustaining current at the data inputs holds the input below the specified VI level.
5. The specified overdrive current at the data input forces the data input to the opposite logic input state.

DEFINITIONS
Short-form specification The data in a short-form
specification is extracted from a full data sheet with the
same type number and title. For detailed information see
the relevant data sheet or data handbook.
Limiting values definition Limiting values given are in
accordance with the Absolute Maximum Rating System
(IEC 60134). Stress above one or more of the limiting
values may cause permanent damage to the device.
These are stress ratings only and operation of the device
attheseoratany other conditions above thosegiveninthe
Characteristics sections of the specification is not implied.
Exposure to limiting values for extended periods may
affect device reliability.

The 74LVC(H)16244A is a high-performance, low power, low voltage, Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families. Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 Volt. These features allow the use of these devices as a mixed 3.3
and 5 V environment.
The 74LVC(H)16244A is a 16-bit non-inverting buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features
four Output Enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.
The 74LVC(H)16244A is identical to the 74LVC16240A but has non-inverting outputs.
The 74LVCH16244A bushold data inputs eliminates the need for external pull-up resistors to hold unused inputs.
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range from 1.2 to 3.6 V
CMOS low power consumption
MULTIBYTETM flow-through standard pin-out architecture
Low inductance multiple power and ground pins for minimum noise and ground bounce
Direct interface with TTL levels
All data inputs have bushold (74LVCH16244A only).
Complies with JEDEC standard no. 8-1A
ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
Specified from -40 to +85 Cel and -40 to +125 Cel.
