description

These 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.

(TOP VIEW)

On the positive transition of the clock (CLK) input,

the Q outputs are set to the complement of the

logic states set up at the data (D) inputs. The

’ALS534A and SN74AS534 have inverted out-

puts, but otherwise are functionally equivalent to

the ’ALS374A and SN74AS374.

A buffered output-enable (OE) input places the

eight outputs in either a normal logic state (high or

low logic levels) or a high-impedance state. In the

high-impedance state, the outputs neither load

nor drive the bus lines significantly. The

high-impedance state and increased drive

provide the capability to drive bus lines without

interface or pullup components.

OE does not affect the internal operations of the flip-flops. Old data can be retained or new data can be entered

while the outputs are off.

The SN54ALS534A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ALS534A and SN74AS534 are characterized for operation from 0°C to 70°C.
