M74HCT139 DUAL 2 TO 4 DECODER/DEMULTIPLEXER s s s s s s HIGH SPEED: tPD = 17ns (TYP.) at VCC = 4.5V LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C COMPATIBLE WITH TTL OUTPUTS : VIH = 2V (MIN.) VIL = 0.8V (MAX) SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 139 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HCT139B1R M74HCT139M1R T&R M74HCT139RM13TR M74HCT139TTR DESCRIPTION The M74HCT139 is an high speed CMOS DUAL TWO LINE TO FOUR LINE DECODER/ DEMULTIPLEXER fabricated with silicon gate C2MOS technology. The active low enable input can be used for gating or as a data input for demultiplexing applications. 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.
