TC7MBL3253CFT/FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MBL3253CFT,TC7MBL3253CFK,TC7MBL3253CFTG Dual 1-of-4 FET Multiplexer/Demultiplexer The TC7MBL3253C is a Low Voltage/Low Capacitance CMOS 2bit 1-of-4 Multiplexer/Demultiplexer. The low on-resistance of the switch allows connections to be made with minimal propagation delay time. This device consists of two individual four-inputs multiplexer/demultiplexer with common select input (S1, S0) and output enable ( OE ). The A input is connected to the B1 to B4 outputs as determined by the combination of both the select input (S1, S0) and output enable ( OE ). When the output enable ( OE ) input is held at “H” level, the switches are open regardless of the state of the select inputs, and a high-impedance state exists between the switches. 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 TC7MBL3253C. 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) = - ( 13 + 15 )E-12 ･ ( 120 + 9) ･ ln ( ( ( 3.0 - 0 ) – 1.5 ) / ( 3.0 – 0 ) ) ≈ 2.5 ns Calculation conditions: VCC = 3.0V, CL = 15pF , RDRIVE = 120 Ω (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 TC7MBL3253C Measure RDRIVE CL VCC GND RDRIVE = output impedance of the previous IC Previous IC TC7MBL3253C Waveform generated with the TC7MBL3253C 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 VCC 項目 VM Figure 3 3.3 ± 0.3 V 2.5 ± 0.2 V 1.8 ± 0.15 V VCC / 2 VCC / 2 VCC / 2 Test Circuit 8 2009-02-02 TC7MBL3253CFT/FK/FTG Package Dimensions Weight: 0.06 g (typ.) 9 2009-02-02 TC7MBL3253CFT/FK/FTG Package Dimensions Weight: 0.02 g (typ.) 10 2009-02-02 TC7MBL3253CFT/FK/FTG Package Dimensions Weight: 0.013 g (typ.) 11 2009-02-02 TC7MBL3253CFT/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.
