description

These octal D-type edge-triggered flip-flops

feature 3-state outputs designed specifically for

bus driving. They are particularly suitable for

implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.

18 2Q

The eight flip-flops enter data on the low-to-high

transition of the clock (CLK) input. The

SN74ALS575A, SN54AS575, and SN74AS575

may be synchronously cleared by taking the clear

(CLR) input low.

The output-enable (OE) input 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

SN54ALS574B,

SN54AS574,

and

SN54AS575 are characterized for operation over

the full military temperature range of –55°C to

125°C. The SN74ALS574B, SN74ALS575A,

SN74AS574, and SN74AS575 are characterized

for operation from 0°C to 70°C.
