M74HCT648 HCT646 OCTAL BUS TRANSCEIVER/REGISTER

The M74HCT646/648 are high speed CMOS OCTAL BUS TRANSCEIVERS AND REGISTERS, 2 (3-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.
