1. General description
The 74LVC541A is an octal non-inverting buffer/line driver with 5 V tolerant inputs and
outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the outpu t, preventing the damaging ba ckflow current through the device
when it is powered down.
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 Vand 5 V applications.
2. Features and benefits
5 V tolerant inputs for interlacing 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
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

5.1 Pinning
5.2 Pin description
(1) This is not a supply pin. The substrate is att ached to
this pad using conductive die attach material. There
is no electrical or mechanical requirement to solder
this pad. However, if it is soldered, the solder land
should remain floating or be connected to GND.
