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 tpd of 4.8 ns at 3.3 V
• 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
• 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/Pulldown Resistors
• All Outputs Have Equivalent 26-Ω Series
Resistors, So No External Resistors Are
Required
• Ioff Supports Partial-Power-Down Mode
Operation
• Latch-Up Performance Exceeds 250 mA Per
JESD 17
• ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)

DESCRIPTION/ORDERING INFORMATION
This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCHR16245A is designed for asynchronous communication between data buses. The
control-function implementation minimizes external-timing requirements.
