TC74LVX4245FS

TC74LVX4245FS TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LVX4245FS Dual Supply Octal Bus Transceiver The TC74LVX4245FS is a dual supply, advanced high-speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. Designed for use as an interface between a 5V bus and a 3.3V bus in mixed 5V/3.3V supply systems’ it achieves high-speed operation while maintaining the CMOS low power dissipation. It is intended for 2 way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input ( G ) can be used to disable the device so that the buses are effectively isolated. The A-port interfaces with the 5V bus, the B-port with the 3.3V bus. Weight: 0.14 g (typ.) All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features Bi-directional interface between 5 V and 3 V buses High-speed: tpd = 6.0 ns (typ.) (VCCA = 5.0 V, VCCB = 3.3 V) Low power dissipation: ICC = 8 μA (max) (Ta = 25°C) Symmetrical output impedance: IOUTA = ±24 mA (min) IOUTB = ±12 mA (min) (VCCA = 4.5 V, VCCB = 3.0 V) Low noise: VOLP = 1.5 V (max) Package: SSOP (shrink small outline package) 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 pin must have their input levels fixed by means of pull up or pull down resistors. Start of commercial production 19...
