description

GND 10

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 ’HC374 devices are

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

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

are set to the logic levels that were set up at the

data (D) inputs.

15 6Q

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 in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54HC374 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74HC374 is characterized for operation from –40°C to 85°C.
