DESCRIPTION:
The FCT3244/A octal buffer/line drivers are built using
advanced dual metal CMOS technology. These high-speed,
low-power buffers are designed to be used as memory data
and address drivers, clock drivers, and bus-oriented transmitter/receivers. The three-state controls are designed to operate these devices in a dual-nibble or single-byte mode. All
inputs are designed with hysteresis for improved noise margin.
