74LVCH322244A
32-bit buffer/line driver; 30
series termination resistors; 5 V
tolerant input/output; 3-state
Rev. 3 — 16 December 2011
Product data sheet
1. General description
The 74LVCH322244A is a 32-bit non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable inputs nOE. A HIGH on input nOE
causes the outputs to assume a high-impedance OFF-state.
The device is designed with 30
series termination resistors in both HIGH and LOW
output stages to reduce line noise.
To ensure the high-impedance state during power-up or power-down, input nOE should
be tied to V
CC
through a pull-up resistor; the minimum value of the resistor is determined
by the current-sinking capability of the driver.
Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can
handle 5 V. These features allow the use of these devices in a mixed 3.3 V and 5 V
environment.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
or floating data inputs at a valid logic level.
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
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
Integrated 30
termination resistors
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
