Buffer/Line Driver 8-CH Inverting 3-ST CMOS 20-Pin SOP-II T/R

Octal Buffer/Line Driver with 3-STATE Outputs

Bus Driver, AHC/VHC Series, 2-Func, 4-Bit, Inverted Output, CMOS, PDSO20

The VHC240 is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC240 is an inverting 3-STATE buffer having two active-LOW output enables. This device is designed to drive buslines or buffer memory address registers. An input protection circuit ensures that 0V 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 backup. This circuit prevents device destruction due to mismatched supply and input voltages.
