74HC620 OCTAL BUS TRANSCEIVER

The M54/74HC620/623 are high speed CMOS OCTAL BUS TRANSCEIVERS fabricated in silicon 2 gate C MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. These octal bus transceivers are designed for asynchronous two-way communication between dat.
