8Bit Priority Encoder
The MC14532B is constructed with complementary MOS (CMOS)
enhancement mode devices. The primary function of a 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).
Diode Protection on All Inputs
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Lowpower TTL Loads or One LowPower

2. Maximum Ratings are those values beyond which damage to the device
may occur.

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
highimpedance 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.
