SCAS545L – OCTOBER 1995 – REVISED JUNE 2014
SN74LVCH162244A 16-Bit Buffer/Driver with 3-State Outputs
1 Features
1 Member of the Texas Instruments
Widebus™ Family
• Operates From 1.65 V to 3.6 V
• Inputs Accept Voltages to 5.5 V
• Max tpd of 4.4 ns at 3.3 V
• Output Ports Have Equivalent 26-Series
Resistors, so No External Resistors are Required
• Typical VOLP (Output Ground Bounce)
<0.8 V at VCC = 3.3 V, TA = 25°C
• Typical VOHV (Output VOH Undershoot)
>2 V at VCC = 3.3 V, TA = 25°C
• Ioff Supports Live Insertion, Partial-Power-Down
Mode, and Back-Drive Protection
• Supports Mixed-Mode Signal Operation on
All Ports
(5-V Input/Output Voltage With 3.3-V VCC)
• Bus Hold on Data Inputs Eliminates the Need for
External Pullup or Pulldown Resistors
• Latch-Up Performance Exceeds 250 mA Per
JESD 17
• ESD Protection Exceeds JESD 22

3 Description
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V VCC operation.
The device can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer.
The SN74LVCH162244A device is designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters.
