74LVC16241A
16-bit buffer/line driver with 5 V tolerant inputs/outputs;
3-state
Rev. 4 — 26 October 2011
Product data sheet
1. General description
The 74LVC16241A is a 16-bit non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable inputs (1OE, 2OE, 3OE and 4OE).
Schmitt trigger action at all inputs makes the circuit highly tolerant of slower input rise and
fall times. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit
buffer.
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.
2. Features and benefits
5 V tolerant inputs and 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 outputs 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
Specified from
