Abstract: HS-C'MOS™ INTEGRATED CIRCUITS 4-ûl OCTAL BUS TRANSCEIVER 3-STATE, INVERTING DESCRIPTION The M54/74HCT640 utilize silicon gate C2MOS technology to achieve operating speed equivalent to LSTTL parts. Along with the low power dissipation and high noise immunity of standard CMOS integrated circuits, it has a fan-out of 15 LSTTL loads. This IC is intended for two-way asynchronous communication between data buses, the direction of data transmission being determined by the DIB input. _ The enable ... OCR Scan
