1 / 8 page MOTOROLA CMOS LOGIC DATA 1 MC14529B Dual 4-Channel Analog Data Selector The MC14529B analog data selector is a dual 4–channel or single 8–channel device depending on the input coding. The device is suitable for digital as well as analog application, including various one–of–four and one–of–eight data selector functions. Since the device has bidirectional analog characteristics it can also be used as a dual binary to 1–of–4 or a binary to 1–of–8 decoder. • Data Paths Are Bidirectional • 3–State Outputs • Linear “On” Resistance • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load over the Rated Temperature Range.

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 ≤ (Vin or Vout) ≤ 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.
