EL5123C, EL5223C, EL5323C, EL5423C - Product Brief
General Description
The EL5123C, EL5223C, EL5323C, and EL5423C are low power,
high voltage rail-to-rail input/output buffers designed primarily for use
in reference voltage buffering applications for TFT_LCDs. They are
available in quad (EL5123C), octal (EL5223C), 10-channel
(EL5323C), and 12-channel (EL5423C) topologies. All buffers feature
a -3dB bandwidth of 12MHz and operate from just 600µA per buffer.
This family also features fast slewing and settling times, as well as a
continuous output drive capability of 30mA (sink and source).
The quad channel EL5123C is available in the 10-pin MSOP package.
The 8-channel EL5223C is available in both the 20-pin TSSOP and
24-pin LPP packages, the 10-channel EL5323C in the 24-pin TSSOP
and 24-pin LPP packages, and the 12-channel EL5423C in the 28-pin
TSSOP and 32-pin LPP packages. All buffers are specified for opera-
tion over the full -40°C to +85°C temperature range.
