FEATURES
• Member of the Texas Instruments Widebus™
Family
• Operates From 1.65 V to 3.6 V
• Inputs Accept Voltages to 5.5 V
• Max t_pd of 4.4 ns at 3.3 V
• Output Ports Have Equivalent 26-Ω Series
Resistors, So No External Resistors Are
Required
• Typical V_OLP (Output Ground Bounce) < 0.8 V
at V_CC = 3.3 V, T_A = 25°C
• Typical V_OHV (Output V_OH Undershoot) > 2 V
at V_CC = 3.3 V, T_A = 25°C
• I_off Supports Partial-Power-Down Mode
Operation
• Supports Mixed-Mode Signal Operation on All
Ports (5-V Input/Output Voltage With
3.3-V V_CC)
• Bus Hold on Data Inputs Eliminates the Need
for External Pullup/Pulldown Resistors
• Latch-Up Performance Exceeds 250 mA Per
JESD 17
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)

DESCRIPTION/ORDERING INFORMATION
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V V_CC operation.
The SN74LVCH162244A is designed specifically to improve both the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit
buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable
(OE) inputs.
