Overview

TC74ACT245,640P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT245P, TC74ACT245F, TC74ACT245FT TC74ACT640P, TC74ACT640F, TC74ACT640FT Octal Bus Transceiver TC74ACT245P/F/FT TC74ACT640P/F/FT 3-State, Non-Inverting 3-State, Inverting TC74ACT245P, TC74ACT640P The TC74ACT245 and 640 are advanced high speed CMOS OCTAL BUS TRANSCEIVERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.

They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

These devices may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS.

Key Features
