3-state octal D-type transparent latches and edge-triggered flip-flops
DM74LS373/DM74LS374
3-STATE Octal D-Type Transparent Latches and
Edge-Triggered Flip-Flops
General DescriptionThese 8-bit registers feature totem-pole 3-STATE outputs
designed specificallyfor driving highly-capacitiveor rela-
tively low-impedance loads. The high-impedance stateand
increased high-logic level drive provide these registers with
the capabilityof being connected directlytoand drivingthe
bus linesina bus-organized system without needfor inter-
faceor pull-up components. Theyare particularly attractive
for implementing buffer registers,I/O ports, bidirectionalbus
drivers,and working registers.
The eight latchesofthe DM54/74LS373are transparent
D-type latches meaningthat whilethe enable(G)is highthe outputswill followthe data(D) inputs. Whenthe enableis
takenlowthe outputwillbe latchedatthe levelofthe data
that wassetup.
The eight flip-flopsof theDM54/74LS374are edge-triggered
D-typeflip flops.Onthe positive transitionof theclock,theQ
outputswillbesettothe logic statesthat weresetupatthe inputs.
Abuffered outputcontrol inputcan beusedto place theeight
outputsin either anormallogicstate(highorlowlogiclevels)a high-impedance state.Inthe high-impedance statethe
outputs neither loadnor drivethebus lines significantly.
The output control doesnot affectthe internal operationof
the latchesor flip-flops. Thatis,theold datacanbe retained new datacanbe entered even whilethe outputsareoff.
