Octal D-Type Edge Triggered Flip-Flops with 3-State Outputs
Package Options Include PlasticSmall-Outline (DW) Packages, Ceramic
Chip Carriers (FK), and Standard Plastic (N)
and Ceramic (J) DIPs
descriptionThese octal D-type edge-triggered flip-flops
feature 3-state outputs designed specifically for
driving highly capacitive or relatively
low-impedance loads. They are particularly
suitable for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working
registers.
On the positive transition of the clock (CLK) input,
the Q outputs are set to the logic levels set up at
the data (D) inputs.
A buffered output-enable (OE) input places the
eight outputs in either a normal logic state (high or
low logic levels) or the high-impedance state. In
the high-impedance state, the outputs neither
load nor drive the bus lines significantly. The
high-impedance state and the increased drive
provide the capability to drive bus lines without
interface or pullup components.
OE does not affect internal operations of the flip-flops. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
The SN54ALS374A and SN54AS374 are characterized for operation over the full military temperature range
of –55°C to 125°C. The SN74ALS374A and SN74AS374 are characterized for operation from 0°C to 70°C.
