The EL5421T is a high voltage rail-to-rail input-output buffer with low power consumption. The EL5421T contains four buffers. Each buffer exhibits beyond the rail input capability, rail-to-rail output capability and is unity gain stable. The maximum operating voltage range is from 4. 5V to 19V. It can be configured for single or dual supply operation, and typically consumes only 500µA per buffer. The EL5421T has an output short circuit capability of ±200mA and a continuous output current capability of ±70mA. The EL5421T features a slew rate of 12V/µs. Also, the device provides common mode input capability beyond the supply rails, rail-to-rail output capability, and a bandwidth of 12MHz (-3dB). This enables the buffers to offer maximum dynamic range at any supply voltage. These features make the EL5421T an ideal buffer solution for use in TFT-LCD panels as a VCOMor static gamma buffer, and in High-Speed filtering and signal conditioning applications. Other applications include battery power and portable devices, especially where low power consumption is important. The EL5421T is available in a space saving 10 Ld MSOP package and operates over an ambient temperature range of -40°C to +85°C.
