TC74VCXR2245FT

The TC74VCXR2245FT is a high performance CMOS OCTAL BUS TRANSCEIVER.Designed for use in 1.8, 2.5 or 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation.It is also designed with over voltage tolerant inputs and outputs up to 3.6 V.The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable the device so that the busses are effectively isolated. The 26-series resistor helps reducing output overshoot and undershoot without external resistor.All inputs are equipped with protection circuits against static discharge.

Features of the TC74VCXR2245FT are:(1)26- series resistors on outputs;(2)low voltage operation:VCC=1.8--3.6 V;(3)high speed operation:tpd=4.4 ns (max) at VCC=3.0~3.6 V, tpd=5.6 ns (max) at VCC=2.3~2.7 V,tpd=9.8 ns (max) at VCC=1.8 V;(4)3.6 V tolerant inputs and outputs;(5)output current:Ioh/IOL=±12 mA (min) at VCC=3.0V,IOH/COL=±8mA (min) at VCC=2.3 V,IOH/COL=±4 mA (min) at VCC=1.8 V;(6)latch-up performance:±300 mA;(7)ESD performance:human body model>±2000 V,machine model>±200 V;(8)package:TSSOP (thin shrink small outline package);(9)bidirectional interface between 2.5 V and 3.3 V signals;(10)power down protection is provided on all inputs and outputs;(11)supports live insertion/withdrawal.

The absolute maximum ratings of the TC74VCXR2245FT can be summarized as:(1)power supply voltages:-0.5 to +4.6 V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 4.6 V;(4)input diode current:-50mA;(5)power dissipation:180mW.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").Unintended Usage include atomic energy control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments,medical instruments, all types of safety devices, etc..
