TC7MBL6125S,6126SFT/FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MBL6125SFT, TC7MBL6125SFK, TC7MBL6125SFTG TC7MBL6126SFT, TC7MBL6126SFK, TC7MBL6126SFTG Quad Low Voltage/Low Capacitance Bus Switch TC7MBL6125S/6126S is low voltage CMOS 4-bit Bus Switch. The low on resistance of the switch allows connections to be made with minimal propagation delay and while maintaining CMOS low power dissipation. The TC7MBL6125S requires the output enable ( OE ) input to be set high to place the output into the high impedance state, whereas the TC7MBL6126S requires the output enable (OE) input to be set low to place the output into high impedance. All inputs are equipped with protection circuits against static discharge.

In practice, the tr(out) and tf(out) values are also affected by the circuit’s capacitance and resistance components other than those of the TC7MBL6125S,6126S. The tr / tf (out) values can be approximated as follows. (Figure 3 shows the test circuit.) tr / tf out (approx) = - ( CI/O + CL ) ･ (RDRIVE+ RON) ･ ln ( ( ( VOH – VOL ) – VM) / ( VOH – VOL ) ) where, RDRIVE is the output impedance of the previous-stage circuit. Calculation example: tr out (approx) = - ( 12 + 15 )E-12 ･ ( 120 + 9) ･ ln ( ( ( 3.0 - 0 ) – 1.5 ) / ( 3.0 – 0 ) ) ≈ 2.4 ns Calculation conditions: VCC = 3.0V , CL = 15pF , RDRIVE = 120Ω(output impedance of the previous IC), VM = 1.5V(VCC / 2) Output of the previous IC = digital (i.e., high-level voltage = VCC; low-level voltage = GND) Previous IC Waveform generated without the TC7MBL6125S, 6126S Measure RDRIVE CL VCC GND RDRIVE = output impedance of the previous TC7MBL6125S TC7MBL6126S Previous IC Waveform generated with the TC7MBL6125S,6126S added RDRIVE An/Bn CI/O (Switch On) Bn/An Measure VOH = VM VM VOL CL RON tr out tf out RDRIVE = output impedance of the previous Parameter VM Figure 3 VCC 3.3 ± 0.3 V 2.5 ± 0.2 V 1.8 ± 0.15 V VCC / 2 VCC / 2 VCC / 2 Test Circuit 7 2007-10-19 TC7MBL6125S,6126SFT/FK/FTG Package Dimensions Weight: 0.06 g (typ.) 8 2007-10-19 TC7MBL6125S,6126SFT/FK/FTG Package Dimensions Weight: 0.02 g (typ.) 9 2007-10-19 TC7MBL6125S,6126SFT/FK/FTG Package Dimensions Weight: 0.013 g (typ.) 10 2007-10-19 TC7MBL6125S,6126SFT/FK/FTG RESTRICTIONS ON PRODUCT USE 20070701-EN GENERAL • The information contained herein is subject to change without notice. • TOSHIBA is continually working to improve the quality and reliability of its products.
