TC74LVX157

The TC74LVX157 is a high speed CMOS quad 2-channel multiplexer fabricated with silicon gate CZMOS technology.Designed for use in 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation. This device is suitable for low voltage and battery operated systems.This device consist of four 2-input digital multiplexers with common select and strobe inputs.

Features of the TC74LVX157 are:(1)high speed:tpd=5.1 ns (Typ)(Vcc=3.3V); (2)low power dissipation:ICC=4A (Max)(Ta=25); (3)input voltage level:VIL=0.8V (Max.) (Vcc=3V),VIH=2.0V (Min.) (Vcc=3 V); (4)power down protection is provided on all inputs; (5)balanced propagation delays:tpLHtpHL; (6)low noise:VOLP=0.5V (Max.); (7)pin and function compatible with 74HC157.An input protection circuit ensures that 0 to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up.This circuit prevents device destruction due to mismatched supply and input voltages.

The absolute maximum ratings of the TC74LVX157 can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 7.0V;(4)input diode current:-20 mA;(5)DC output voltage:-0.5 to Vcc+0.5V;(6)power dissipation:180mW.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
