M74HC648 - 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,
