FK PACKAGE (TOP VIEW) 1A 1G NC VCC 2G description/ordering information The 'HCT139 devices are designed for high-performance memory-decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, these decoders can minimize the effects of system decoding. When employed with high-speed memories utilizing a fast enable circuit, the delay time of these decoders and the enable time of the memory usually are less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible. 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2A 2B NC 2Y0 2Y1 1Y3 GND NC 2Y3 2Y2 1B 1Y0 NC 1Y1 1Y2 NC - No internal connection ORDERING INFORMATION PACKAGE TA PDIP - N TOP-SIDE MARKING Tube of 25 SN74HCT139N Tube of 40 SN74HCT139D Reel of 2500 SN74HCT139DR Reel of 250 SN74HCT139DT Reel of 2000 SN74HCT139DBR Reel of 2000 SN74HCT139PWR Reel of 250 SN74HCT139PWT CDIP - J Tube of 25 SNJ54HCT139J SNJ54HCT139J CFP - W Tube of 150 SNJ54HCT139W SNJ54HCT139W LCCC - FK Tube of 55 SNJ54HCT139FK SOIC - D -40C -40 C to 85 85C C SSOP - DB TSSOP - PW -55C -55 C to 125 125C C ORDERABLE PART NUMBER SN74HCT139N HCT139 HT139 HT139 SNJ54HCT139FK Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 1 SCLS066D - MARCH 1982 - REVISED SEPTEMBER 2003 description/ordering information (continued) The 'HCT139 devices comprise two individual 2-line to 4-line decoders in a single package. The active-low enable (G) input can be used as a data line in demultiplexing applications. These decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its driving circuit.
