SN54LVTH162244 Datasheet, PDF (1/15 Pages) Texas Instruments – 3.3-V ABT 16-BIT BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

D Members of the Texas Instruments
Widebus  Family
D Output Ports Have Equivalent 22-Ω Series
Resistors, So No External Resistors Are
Required
D Support Mixed-Mode Signal Operation
(5-V Input and Output Voltages With
3.3-V V_CC )
D Support Unregulated Battery Operation
Down to 2.7 V
D Typical V_OLP (Output Ground Bounce)
<0.8 V at V_CC = 3.3 V, T_A = 25°C
D I_off and Power-Up 3-State Support Hot
Insertion
D Bus Hold on Data Inputs Eliminates the
Need for External Pullup/Pulldown
Resistors
D Distributed V_CC and GND Pins Minimize
High-Speed Switching Noise
D Flow-Through Architecture Optimizes PCB
Layout
D Latch-Up Performance Exceeds 500 mA Per
JESD 17
D ESD Protection Exceeds JESD 22

description/ordering information
The ’LVTH162244 devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V_CC operation,
but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as
four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical
active-low output-enable (OE) inputs.
