TC7MBL3125C,3126CFT/FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MBL3125CFT,TC7MBL3125CFK,TC7MBL3125CFTG TC7MBL3126CFT,TC7MBL3126CFK,TC7MBL3126CFTG Low Voltage/Low Capacitance Quad Bus Switch The TC7MBL3125C and TC7MBL3126C are a Low Voltage/Low Capacitance CMOS 4bit Bus Switch. The low on-resistance of the switch allows connections to be made with minimal propagation delay time. The TC7MBL3125C requires the output enable ( OE ) input to be set high to place the output into the high impedance state,whereas the TC7MBL3126C requires the output enable (OE) input to be set low to place the output into the 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 TC7MBL3125C, 3126C. The tr(out) / tf(out) values can be approximated as follows. (Figure 3 shows the test circuit.) tr(out) / 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) = - ( 7.5 + 15 )E-12 ･ ( 120 + 6.5) ･ ln ( ( ( 3.0 - 0 ) – 1.5 ) / ( 3.0 – 0 ) ) ≈ 2.0 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 TC7MBL3125C,3126C Measure RDRIVE CL VCC GND RDRIVE = output impedance of the previous IC TC7MBL3125C TC7MBL3126C Previous IC Waveform generated with the TC7MBL3125C,3126C 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 IC Symbol 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 8 2008-10-01 TC7MBL3125C,3126CFT/FK/FTG Package Dimensions Weight: 0.06 g (typ.) 9 2008-10-01 TC7MBL3125C,3126CFT/FK/FTG Package Dimensions Weight: 0.02 g (typ.) 10 2008-10-01 TC7MBL3125C,3126CFT/FK/FTG Package Dimensions Weight: 0.013 g (typ.) 11 2008-10-01 TC7MBL3125C,3126CFT/FK/FTG RESTRICTIONS ON PRODUCT USE • Toshiba Corporation, and its subsidiaries and affiliates (collectively “TOSHIBA”), reserve the right to make changes to the information in this document, and related hardware, software and systems (collectively “Product”) without notice. • This document and any information herein may not be reproduced without prior written permission from TOSHIBA.
