DESCRIPTION
The 16-bit wide UT54ACTQ16244 buffer/line driver is built
using Aeroflex’s Commercial RadHard^TM epitaxial CMOS
technology and is ideal for space applications. This high speed,
low power UT54ACTQ16244 buffer/line driver is designed to
improve the performance and density of three-state memory
address drivers, clock drivers, and bus-oriented receivers and
transmitters. The UT54ACTQ16244 can be used as four 4-bit
(nibble) buffers, two 8-bit (byte) buffers, or one 16-bit buffer.
The device provides true outputs and symmetrical OE (active-
low) output-enable inputs. The device is nibble controlled with
each nibble functioning identically, but independent of each oth-
er. The control pins can be shorted together to obtain full 16-bit
operation.
