Objective data sheet
7.2.2 LCD interfaces, medium-speed interfaces
7.2.3 Keypad, low-speed interfaces
To generate SDHC and MMC-compliant digital signals, the driver strength should not
significantly undercut 8 mA.
For digital interfaces such as LCD interfaces running at clock speeds between 10 MHz
and 25 MHz or more, IP4251, IP4252 or IP4254 can be used depending on the sink load,
clock speed, driver strength and rise and fall time requirements. Also the minimum
EMI filter requirements may be a decision-making factor.
Especially for lower-speed interfaces such as keypads, low-speed serial interfaces
(e.g. Recommended Standard (RS) 232) and low-speed control signals,
IP4253 (R
ESD protection and strong suppression of unwanted frequencies (EMI filtering).
