1 MC4532B 8-Bit Priority Encoder The MC4532B is cotructed 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 (D thru ) and an enable input () are provided. Five outputs are available, three are address outputs (Q thru ), one group select () and one enable output ( ). Features Diode Protection on All Inputs Supply Voltage Range = 3. to 8 Capable of Driving Two LowPower TTL Loads or One LowPower Schottky TTL Load over the Rated Temperature Range NLV Prefix for Automotive and Other Applicatio Requiring Unique Site and Control Change Requirements; AECQ Qualified and PPAP Capable This Device is PbFree and is RoHS Compliant MAIMUM RATIN (Voltages Referenced to V SS ) Rating Symbol Value Unit DC Supply Voltage Range.5 to +8.

If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.. Temperature Derating: D/DW Package: 7. mw/ C From 65 C To 25 C This device contai protection circuitry to guard agait damage due to high static voltages or electric fields. However, precautio must be taken to avoid applicatio of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation, V in and V out should be cotrained to the range V SS (V in or V out ). Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V SS or ). Unused outputs must be left open.

Two MC4532B s Cascaded for 4Bit Output V SS DIGITAL TO ANALOG CONVERSION The digital eightbit word to be converted is applied to the inputs of the MC452 with the most significant bit at 7 and the least significant bit at. A clock input of up to 2.5 MHz (at = V) is applied to the MC452B. A compromise between I bias for the MC7 and R between N and Pchannel outputs gives a value of R of 33 k. In order to filter out the switching frequencies, RC should be about. ms (if R = 33 k, C.3 F). The analog 3. db bandwidth would then be dc to. khz. ANALOG TO DIGITAL CONVERSION An analog signal is applied to the analog input of the MC7. A digital eightbit word known to represent a digitized level less than the analog input is applied to the MC452 as in the D to A conversion. The word is incremented at rates sufficient to allow steady state to be reached between incrementatio (i.e. 3. ms). The output of the MC7 will change when the digital input represents the first digitized level above the analog input. This word is the digital representation of the analog word.
