TC74LCX163245FT

TC74LCX163245FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX163245FT 16-Bit Dual Supply Bus Transceiver The TC74LCX163245FT is a dual supply, advanced high-speed CMOS 16-bit dual supply voltage interface bus transceiver fabricated with silicon gate CMOS technology. Designed for use as an interface between a 3.3-V or a 2.5-V bus and a 5-V bus in mixed 3.3-V or 2.5-V/5-V supply systems, it achieves high- speed operation while maintaining the CMOS low power dissipation. It is intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. Weight: 0.25 g (typ.) The enable input ( OE ) can be used to disable the device so that the buses are effectively isolated. The B-port interfaces with the 3.3-V or 2.5-V bus, the A-port with the 5 V bus. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features (Note) Bidirectional interface between 3.3 V or 2.5 V buses and 5 V buses Wide operating temperature range: Topr = -40 to 125 °C (Note 1) High-speed operation: tpd = 7.0 ns (max) (VCCB = 3.3 ± 0.3 V / VCCA = 5 ± 0.5 V, Ta = −40 to 85°C) Low power dissipation: ICC = 80 µA (max) (Ta = −40 to 85°C) Symmetrical ouput impedance: IOUTB = ±24 mA (min) IOUTA = ±24 mA (min) (VCCB = 3.0 V / VCCA = 4.5 V) Power-down protection provided on all inputs and outputs Allows A port and VCCA to float simultaneously in ...
