General Description

The EL5127C, EL5227C, EL5327C, and EL5427C are low power, high voltage rail-to-rail input/output buffers designed for use in refer ence voltage buffering applications in small LCD displays. They are available in quad (EL5127C), octal (EL5227C), 10-channel (EL5327C), and 12-channel (EL5427C) topologies. All buffers feature a -3dB bandwidth of 2.5MHz and operate from just 120µA per buffer. This family also features a continuous output drive capability of 30mA (sink and source).
