MOS
technology. They have the same high speed
performance of LSTTL combined with true CMOS
low power consumption. These devices consist of
bustransceiver circuits, D-type flip-flops, and control
circuitry arranged for multiplexed transmission of
data directly from the input bus or from the internal
storage registers. Enable GAB and GBA are
provided to control the transceiver functions. Select
AB and Select BA control pins are provided to select
whether real-time orstored data is transfered. A low
input level selects real-time data, and a high selects
stored data.Data on the A or Bbus, or both, can be
stored in the internal D flip-flops by low-to-high
transitions atthe appropriate clock pins (CLOCK AB
or CLOCK BA) regardless of the select or enable
controlpins. When selectABand selectBAareinthe
real-time transfer mode, it is also possible to store
data without using the internal D-type flip-flops by
simultaneously enabling GAB and GBA. In this
configuration each output reinforces its input. Thus,
when all other data sources to the two sets of bus
linesareathigh impedance, each set ofbus lineswill
remain at its last state. All inputs are equipped with
protection circuits against static discharge and
transient excess voltage.This integrated circuit has
input and output characteristics that are fully
compatible
with

M54/74HCT devices are designed to directly
interface HSCMOS systems with TTL and NMOS
components. Theyarealso plug in replacements for
LSTTL devices giving a reduction
consumption.
