SN74LVCHR16245A
SCAS582Q – NOVEMBER 1996 – REVISED OCTOBER 2014
SN74LVCHR16245A 16-Bit Bus Transceiver 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 t_pd of 4.8 ns at 3.3 V
• 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
• 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 or Pulldown Resistors
• All Outputs Have Equivalent 26-Ω Series
Resistors, So No External Resistors Are Required
• I_off 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
– 2000-V Human-Body Model
– 200-V Machine Model
2 Applications
• Telecom Infrastructures
• Industrial Transport
• Wireless Infrastructures
• Servers
• Tests and Measurements
3 Description
This 16-bit (dual-octal) noninverting bus transceiver is
designed for 1.65-V to 3.6-V V_CC operation.
The SN74LVCHR16245A device is designed for
asynchronous communication between data buses.
The control-function implementation minimizes
external-timing requirements.
