| MM74HC139 Dual 2-To-4 Line Decoder September 1983 Revised December 2003 MM74HC139 Dual 2-To-4 Line Decoder General Description 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. 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. 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. Features s Typical propagation delays -- Select to outputs (4 delays): 18 ns Select to output (5 delays): 28 ns Enable to output: 20 ns s Low power: 40 W quiescent supply power s Fanout of 10 LS-TTL devices s Input current maximum 1 A, typical 10 pA Ordering Code: Order Number MM74HC139M (Note 1) MM74HC139SJ MM74HC139MTC (Note 1) MM74HC139N Package Number M16A M16D MTC16 N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Note 1: Devices also available in Tape and Reel.

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 AC Electrical Characteristics VCC = 5V, TA = 25C, CL = 15 pF, tr = tf = 6 ns Symbol tPHL, tPLH Parameter Maximum Propagation 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 19 30 ns 28 38 ns Conditions Typ 18 Guaranteed Limit 30 Units ns AC Electrical Characteristics CL = 50 pF, tr = tf = 6 ns (unless otherwise specified) Symbol Parameter Conditions (Note 6) VCC 2.0V 4.5V 6.0V (Note 7) 2.0V 4.5V 6.0V 2.0V 4.5V 6.0V 2.0V 4.5V 6.0V CIN CPD Maximum Input Capacitance Power Dissipation Capacitance (Note 8) Note 6: 4 levels of delay are A to Y1, Y3 and B to Y2, Y3.
