M74HC139M1R
M74HC139 DUAL 2 TO 4 DECODER/DEMULTIPLEXER s s s s s s s HIGH SPEED: tPD = 13ns (TYP.) at VCC = 6V LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C HIGH NOISE IMMUNITY: VNIH = V NIL = 28 % VCC (MIN.) SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 139 DESCRIPTION The M74HC139 is an high speed CMOS QUAD 2-INPUT NAND GATE fabricated with silicon gate C2MOS technology. The active low enable input can be used for gating or as a data input for demultiplexing applications. DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC139B1R M74HC139M1R T&R M74HC139RM13TR M74HC139TTR While the enable input is held high, all four outputs are high independently of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage. PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/9
