FK PACKAGE (TOP VIEW) 1A 1G NC VCC description/ordering information The ’AHCT139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 4.5-V to 5.5-V VCC operation. These devices are designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, these decoders can be used to minimize the effects of system decoding. When used with high-speed memories utilizing a fast enable circuit, the delay times 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 2G D D NC – No internal connection ORDERING INFORMATION PDIP – N SN74AHCT139N Tube SN74AHCT139D Tape and reel SN74AHCT139DR SOP – NS Tape and reel SN74AHCT139NSR AHCT139 SSOP – DB Tape and reel SN74AHCT139DBR HB139 Tube SN74AHCT139PW Tape and reel SN74AHCT139PWR TVSOP – DGV Tape and reel SN74AHCT139DGVR HB139 CDIP – J Tube SNJ54AHCT139J SNJ54AHCT139J CFP – W Tube SNJ54AHCT139W SNJ54AHCT139W LCCC – FK Tube SNJ54AHCT13FK SNJ54AHCT139FK TSSOP – PW –55°C to 125°C TOP-SIDE MARKING Tube SOIC – D –40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA SN74AHCT139N AHCT139 HB139 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
