SN74LVCHR16245A
SCAS582Q â NOVEMBER 1996 â REVISED OCTOBER 2014
SN74LVCHR16245A 16-Bit Bus Transceiver With 3-State Outputs
1 Features
â¢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 4.8 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 or Pulldown Resistors
⢠All Outputs Have Equivalent 26-⦠Series
Resistors, So No External Resistors Are Required
⢠Ioff Supports Live Insertion, Partial Power-Down
Mode, and Back-Drive Protection
⢠Latch-Up Performance Exceeds 250 mA
Per JESD 17
⢠ESD Protection Exceeds JESD 22

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