Overview
The LC7464M is a 64-key infrared remote control trans-
mitter IC that incorporates all key-scanning, oscillator and
timing function on-chip, resulting in a very low external
component count.
The LC7464M generates 71 function codes using the 64
function keys. The output data format comprises the mask-
programmed custom code, the parity field, the mask-pro-
grammed system code, the product code, the function code
and the data check code.
The LC7464M operates from a 2.0 to 3.6 V supply and is
available in 24-pin MFPs.
