The NTE4532B is an 8−bit priority encoder in a 16−lead DIP-type package constructed with complementary MOS (CMOS) enhancement mode devices. The primary function of the priority encoder is to provide a binary address for the active input with the highest priority. Eight data inputs (D0 thru D7) and an enable input (Ein) are provided. Five outputs are available, three are address outputs (Q0 thru Q2), one group select (GS) and one enable output (Eout).
VDD: −0.5 to +18.0V
Vin: −0.5 to VDD to +0.5V
I (per pin): 10mA
TA: −55° to +125°C
Tstg: −65° to +150°C

* This device contains circuitry to protect the input against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance
circuit. For proper operation it is recommended that Vin and Vout 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).
