... HIGH-going signal at input nRD as shown in the function table. Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower input rise and fall times. The 74HC123; 74HCT123 are identical to the 74HC423; 74HCT423 but can be triggered via the reset input. 2. Features ...
