SEMICONDUCTOR TECHNICAL DATA
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
ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎSchottky TTL Load over the Rated Temperature Range.

Impedance
This device contains protection circuitry to guard against damage
due to high static voltages or electric fields. 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.
