74LVC2244A
Octal buffer/line driver; 30 series termination; 5 V tolerant
input/output; 3-state
Rev. 5 — 3 November 2011
Product data sheet
1. General description
The 74LVC2244A is an octal non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable input pins 1OE and 2OE. A HIGH on
pin nOE causes the outputs to assume a high-impedance OFF-state. Schmitt trigger
action at all inputs makes the circuit highly tolerant for slower input rise and fall times. The
device is designed with 30 series termination resistors in both HIGH and LOW output
stages to reduce line noise.
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 as translators in
mixed 3.3 V and 5 V applications.
2. 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
Direct interface with TTL levels
Integrated 30 termination resistors
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-A115B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Specified from 40 C to +85 C and 40 C to +125 C
