TC74VCX164245FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX164245FT 16-Bit Dual Supply Bus Transceiver The TC74VCX164245FT is a dual supply, advanced high-speed CMOS 16-bit bus transceiver fabricated with silicon gate CMOS technology. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. Designed for use as an interface between a 3.3-V or 2.5-V bus and a 2.5-V or 1.8-V bus in mixed 3.3-V or 2.5-V/2.5-V or 1.8-V supply systems. The B-port interfaces with the 3.3-V or 2.5-V bus, the A-port with the 2.5-V or 1.8-V bus. Weight: 0.25 g (typ.) The direction of data transmission is determined by the level of the DIR input. The enable input ( OE ) can be used to disable the device so that the buses are effectively isolated. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features (Note) Bidirectional interface between 3.3 V and 2.5 V, 3.3 V and 1.8 V, 2.5 V and 1.8 V High-speed: t = 4.6 ns (max) (V = 3.3 0.3 V, V = 2.5 0.2 V) pd CCB CCA t = 7.1 ns (max) (V = 3.3 0.3 V, V = 1.8 0.15 V) pd CCB CCA t = 7.0 ns (max) (V = 2.5 0.2 V, V = 1.8 0.15 V) pd CCB CCA 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 Latch-up performance: 300 mA ESD performance: Machine model 200 V Human body model 2000 V Package: TSSOP 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 level fixed by means of pull-up or pull-down resistors.
