Product data sheet Rev. 06 — 11 January 2010 5 of 27 NXP Semiconductors 74HC4052; 74HCT4052 Dual 4-channel analog multiplexer/demultiplexer 7. Functional description 7.1 Function table [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care. 8. Limiting values [1] To avoid drawing VCC current out of pins nZ, when switch current flows in pins nYn, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into pins nZ, no VCC current will flow out of pins nYn. In this case there is no limit for the voltage drop across the switch, but the voltages at pins nYn and nZ may not exceed VCC or VEE. [2] For DIP16 packages: above 70 °C the value of P tot derates linearly with 12 mW/K. For SO16 packages: above 70 °C the value of P tot derates linearly with 8 mW/K. For SSOP16 and TSSOP16 packages: above 60 °C the value of P tot derates linearly with 5.5 mW/K. For DHVQFN16 packages: above 60 °C the value of P tot derates linearly with 4.5 mW/K. Table 3. Function table[1] Input Channel on E S1 S0 L L L nY0 and nZ L L H nY1 and nZ L H L nY2 and nZ L H H nY3 and nZ H X X none Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to VEE = GND (ground = 0 V).
