TC74HCT139AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT139AP, TC74HCT139AF Dual 2-to-4 Line Decoder The TC74HCT139A is a high speed CMOS 2-to-4 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. The active low enable input can be used for gating or it can be used as a data input for demultiplexing applications. When the enable input is held “H”, all four outputs are fixed at a high logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: tpd = 17 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIH = 2 V (min) VIL = 0.8 V (max) • Wide interfacing ability: LSTTL, NMOS, CMOS • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Pin and function compatible with 74LS139 Pin Assignment TC74HCT139AP TC74HCT139AF Weight DIP16-P-300-2.54A SOP16-P-300-1.27A : 1.00 g (typ.) : 0.18 g (typ.)

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW. 2 2014-03-01 Operating Ranges (Note) TC74HCT139AP/AF Characteristics Symbol Rating Unit Supply voltage Input voltage Output voltage Operating temperature Input rise and fall time VCC VIN VOUT Topr tr, tf 4.5 to 5.5 V 0 to VCC V 0 to VCC V −40 to 85 °C 0 to 500 ns Note: The operating ranges must be maintained to ensure the normal operation of the device.
