|
The M54/74HC245, HC640 and HC643 utilise silicon gate C2MOS technology to achive operating speeds equivalent to LSTTL devices. Along with the low power dissipation and high noise 2 immunity of standards C MOS integrated circuit, it possesses the capability to drive 15 LSTTL loads. These IC’s are intended for two-way asynchronous munication between data buses, and the direction of data trasmission is determined by...
