Two select (S0 and S1) inputs control the data flow. A clock (CLK) and a clock enable (CLKEN) synchronize the device operation. When CLKEN is high, the bus switch remains in the last clocked function. 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 S0 S1 ORDERING INFORMATION TA –40°C to 85°C PACKAGE SSOP – DL TSSOP – DGG (1) (2) (1) (2) ORDERABLE PART NUMBER Tube SN74CBT16232DL Tape and reel SN74CBT16232DLR Tape and reel SN74CBT16232DGGR TOP-SIDE MARKING CBT16232 CBT16232 Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. The package thermal impedance is calculated in accordance with JESD 51-7.

This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. Measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages of the two (A or B) terminals.
