M74HC646 HC648 OCTAL BUS TRANSCEIVER/REGISTER

The M74HC646/648 are high speed CMOS OCTAL BUS TRANSCEIVERS AND REGISTERS, (32 STATE) fabricated in silicon gate C MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. These devices consist of bus transceiver circuits with 3-state output, .
