SN74LVC2244A
- Operates From 1.65 V to 3.6 V
- Inputs Accept Voltages to 5.5 V
- Max tpd of 5.5 ns at 3.3 V
- Output Ports Have Equivalent 26-Ω 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 - Supports Mixed-Mode Signal Operation on
All Ports (5-V Input/Output Voltage With
3.3-V VCC) - 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 (A114-A)
- 200-V Machine Model (A115-A)
- 1000-V Charged-Device Model (C101)
The SN74LVC2244A octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.
