description

These 8-bit 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.

The eight flip-flops of the ’HC534 are

edge-triggered D-type flip-flops. On the positive

transition of the clock (CLK) input, the Q outputs

are set to the complement of the logic states that

were set up at the data (D) inputs. The ’HC534 are

functionally equivalent to the ’HC374, but the

’HC534 have inverted outputs.

An 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 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 SN54HC534 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HC534 is characterized for operation from –40°C to 85°C.
