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 display interfaces running at clock speeds between
10 MHz and 25 MHz or more, IP4251, IP4252, or IP4254 can be used in dependency of
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.
RS232) and low-speed control signals, IP4253 (R
