74VHC157FT  
CMOS Digital Integrated Circuits Silicon Monolithic  
74VHC157FT  
1. Functional Description  
Quad 2-Channel Multiplexer  
2. General  
The 74VHC157FT is an advanced high speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with silicon  
gate C2MOS technology.  
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS  
low power dissipation.  
It consists of four 2-input digital multiplexers with common select and strobe inputs.  
When the ST input is held "H" level, selection of data is inhibited and all the outputs become "L" level.  
The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs.  
An Input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply  
voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back  
up. This circuit prevents device destruction due to mismatched supply and input voltages.  
3. Features  
(1) AEC-Q100 (Rev. H) (Note 1)  
(2) Wide operating temperature: Topr = -40 to 125  
(3) High speed: tpd = 4.1 ns (typ.) at VCC = 5 V  
(4) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25   
(5) High noise immunity: VNIH = VNIL = 28 % VCC (min)  
(6) Power down protection is provided on all inputs.  
(7) Balanced propagation delays: tPLH tPHL  
(8) Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V  
(9) Low noise: VOLP = 0.8 V (max)  
(10) Pin and function compatible with the 74 serise (AC/HC/AHC/LV etc.) 157 type.  
Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales  
representative.
