Revised December 2003 MM74HC139 Dual 2-To-4 Line Decoder General Description Features The MM74HC139 decoder utilizes advanced silicon-gate CMOS technology, and is well suited to memory address decoding or data routing applications. It possesses the high noise immunity and low power consumption usually associated with CMOS circuitry, yet has speeds comparable to low power Schottky TTL logic. ■ Typical propagation delays — The MM74HC139 contain two independent one-of-four decoders each with a single active low enable input (G1, or G2). Data on the select inputs (A1, and B1 or A2, and B2) cause one of the four normally high outputs to go LOW. ■ Fanout of 10 LS-TTL devices Select to outputs (4 delays): 18 ns Select to output (5 delays): 28 ns Enable to output: 20 ns ■ Low power: 40 µW quiescent supply power ■ Input current maximum 1 µA, typical 10 pA The decoder’s outputs can drive 10 low power Schottky TTL equivalent loads, and are functionally as well as pin equivalent to the 74LS139. All inputs are protected from damage due to static discharge by diodes to VCC and ground.

Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. 3 www.fairchildsemi.com MM74HC139 Absolute Maximum Ratings(Note 2) MM74HC139 AC Electrical Characteristics VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6 ns Symbol Parameter tPHL, tPLH Conditions Typ Maximum Propagation Guaranteed Limit Units 18 30 ns 28 38 ns 19 30 ns Delay, Binary Select to any Output 4 levels of delay tPHL, tPLH Maximum Propagation Delay, Binary Select to any Output 5 levels of delay tPHL, tPLH Maximum Propagation Delay, Enable to any Output AC Electrical Characteristics CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol Parameter tPHL, tPLH Maximum Propagation Conditions (Note 6) Delay Binary Select to any Output 4 levels of delay tPHL, tPLH Maximum Propagation (Note 7) TA = 25°C Typ TA = −40 to 85°C TA = −55 to 125°C 2.0V 110 175 219 4.5V 22 35 44 254 51 6.0V 18 30 38 44 2.0V 165 220 275 320 4.5V 33 44 55 64 Output 5 levels of delay 6.0V 28 38 47 54 2.0V 115 175 219 254 Delay Enable to any 4.5V 23 35 44 51 Output 6.0V 19 30 38 44 110 tTLH, tTLH Maximum Output Rise and Fall Time 2.0V 30 75 95 4.5V 8 15 19 22 6.0V 7 13 16 19 3 10 10 10 Maximum Input Units Guaranteed Limits Delay Binary Select to any tPHL, tPLH Maximum Propagation CIN VCC ns ns ns ns pF Capacitance CPD Power Dissipation (Note 8) 75 Capacitance (Note 8) Note 6: 4 levels of delay are A to Y1, Y3 and B to Y2, Y3.
