MC14598B 8-Bit Bus-Compatible Latches
The MC14598B is an 8-bit latch addressed with an external binary address. The 8 latch-outputs are high drive, three-state and bus line compatible. The drive capability allows direct applications with MPU systems such as the Motorola 6800 family. The latches of the MC14598B are accessed via the Address pins, A0, A1, and A2. All 8 outputs from the latches are available in parallel when Enable is in the low state. Data is entered into a selected latch from the Data pin when the Strobe is high. Master reset is available on both parts.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. Publication Order Number: MC14598B/D
