Product Summary
The SN74LVCR2245ARGYR is an octal bus transceiver. This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74LVCR2245ARGYR is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. All outputs, which are designed to sink up to 12 mA, include equivalent 26-W resistors to reduce overshoot and undershoot.
Parametrics
SN74LVCR2245ARGYR absolute maximum ratings: (1)VCC, Supply voltage range: 0.5 to 6.5 V; (2)VI, Input voltage range: -0.5 to 6.5 V; (3)VO, Voltage range applied to any output in the high-impedance or power-off state: -0.5 to 6.5 V; (4)VO, Voltage range applied to any output in the high or low state: -0.5 VCC +0.5 V; (5)IIK, Input clamp current VI < 0: -50 mA; (6)IOK, Output clamp current VO < 0: -50 mA; (7)IO, Continuous output current: ±50 mA; (8)Continuous current through VCC or GND: ±100 mA.
Features
SN74LVCR2245ARGYR features: (1)Operates From 1.65 V to 3.6 V ; (2)Supports Mixed-Mode Signal Operation on All Ports (5-V Input/Output Voltage With 3.3-V VCC); (3)Inputs Accept Voltages to 5.5 V ; (4)Max tpd of 6.3 ns at 3.3 V; (5)Ioff Supports Partial-Power-Down Mode Operation; (6)All Outputs Have Equivalent 26-W Series Resistors, So No External Resistors Are Required; (7)Latch-Up Performance Exceeds 250 mA Per JESD 17; (8)Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25℃; (9)ESD Protection Exceeds JESD 22, 2000-V Human-Body Model (A114-A); 1000-V Charged-Device Model (C101); (10)Typical VOHV (Output VOH Undershoot) >2 V at VCC = 3.3 V, TA = 25℃.
