TC74VCX245FK CMOS Digital Integrated Circuits Silicon Monolithic TC74VCX245FK 1. Functional Description Low-Voltage Octal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs 2. General The TC74VCX245FK is a high performance CMOS octal bus transceiver which is guaranteed to operate from 1.2 V to 3.6 V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V 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. All inputs are equipped with protection circuits against static discharge. 3. Features (Note) (1) Low-voltage operation: V = 1.2 to 3.6 V CC (2) High-speed operation: t = 3.5 ns (max) (V = 3.0 to 3.6 V) pd CC t = 4.2 ns (max) (V = 2.3 to 2.7 V) pd CC t = 8.4 ns (max) (V = 1.65 to 1.95 V) pd CC t = 16.8 ns (max) (V = 1.4 to 1.6 V) pd CC t = 42.0 ns (max) (V = 1.2 V) pd CC (3) Output current: I /I = 24 mA (min) (V = 3.0 V) OH OL CC I /I = 18 mA (min) (V = 2.3 V) OH OL CC I /I = 6 mA (min) (V = 1.65 V) OH OL CC I /I = 2 mA (min) (V = 1.4 V) OH OL CC (4) Bidirectional interface between 2.5 V and 3.3 V signals (5) 3.6 V tolerant function and power-down protection provided on all inputs and outputs. Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down resistors.
