74LVC241A
Octal buffer/line driver with 5 V tolerant inputs/outputs;
3-state
Rev. 5 — 16 December 2011
Product data sheet
1. General description
The 74LVC241A is an octal non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable inputs (pins 1OE and 2OE). Schmitt
trigger action at all inputs makes the circuit highly tolerant of slower input rise and fall
times.
Inputs can be driven from either 3.3 V or 5.0 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
Supply voltage range from 1.2 V to 3.6 V
CMOS low-power consumption
Direct interface with TTL levels
High-impedance when V
CC
= 0 V
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
