This device can be used for memory interleaving, where two different banks of memory need to be addressed simultaneously. The device can be used as two 8-bit to 16-bit multiplexers or as one 16-bit to 32-bit multiplexer. Two select (SEL1 and SEL2) inputs control the data flow. When the TEST inputs are asserted, the A port is connected to both the B1 and the B2 ports. SEL1, SEL2, and the TEST inputs can be driven with a 5-V CMOS, a 5-V TTL, or a low-voltage TTL driver. This device is designed so it does not have through current when switching directions. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 1B1 1B2 2A 3B1 3B2 4A 5B1 5B2 6A 7B1 7B2 8A GND VCC 9B1 9B2 10A 11B1 11B2 12A 13B1 13B2 14A 15B1 15B2 16A SEL1 SEL2 ORDERING INFORMATION Tube SN74CBT16233DL Tape and reel SN74CBT16233DLR TSSOP – DGG Tape and reel SN74CBT16233DGGR TVSOP – DGV Tape and reel SN74CBT16233DGVR SSOP – DL –40°C 40°C to 85°C ORDERABLE PART NUMBER PACKAGE† TA TOP-SIDE MARKING CBT16233 CBT16233 CY233 † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.
