SN74LVCHR16245A
- 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-Ω 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
- 2000-V Human-Body Model
- 200-V Machine Model
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.
