74LVCH16541A
16-bit buffer/line driver; 3-state
Rev. 3 — 15 February 2012
Product data sheet
1. General description
The 74LVCH16541A is a 16-bit buffer/line driver with 3-state outputs. The 3-state outputs
are controlled by the output enable inputs (1OEn and 2OEn). A HIGH on nOEn causes
the outputs to assume a high-impedance OFF-state.
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.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
inputs.
2. Features and benefits
5 Volt 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
All data inputs have bus hold
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-A115-B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Specified from
40 C
to +85
C
and
40 C
to +125
C.
