General Description

The EL5127C, EL5227C, EL5327C, and EL5427C are low power, high voltage rail-to-rail input/output buffers designed for use in reference 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).

The quad channel EL5127C is available in the 10-pin MSOP package. The 8-channel EL5227C is available in both the 20-pin TSSOP and 24-pin LPP packages, the 10-channel EL5327C in the 24-pin TSSOP and 24-pin LPP packages, and the 12-channel EL5427C in the 28-pin TSSOP and 32-pin LPP packages. All buffers are specified for operation over the full -40°C to +85°C temperature range.
