description
These 8-bit flip-flops feature 3-state outputs designed specifically driving highly capacitive relatively low-impedance loads. They particularly suitable implementing buffer registers, ports, bidirectional drivers, working registers. eight flip-flops SN54ABT374 SN74ABT374A edge-triggered D-type flip-flops. positive transition clock (CLK) input, outputs logic levels data inputs.
buffered output-enable (OE) input used place eight outputs either normal logic state (high logic levels) high-impedance state. high-impedance state, outputs neither load drive lines significantly. high-impedance state increased drive provide capability drive lines without need interface pullup components. does affect internal operations flip-flop. data retained data entered while outputs high-impedance state. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. SN54ABT374 characterized operation over full military temperature range -55°C 125°C. SN74ABT374A characterized operation from -40°C 85°C.
