Low-end (sinks)[edit]
| Chip | VDD | Bits | Packages | Eval |
|---|---|---|---|---|
| ✓STP08/16C596 | down to 4.5V | 8/16 | DIP, SO | current limited, can sub for the DP05 in a pinch |
| ✓STP08/16DP05 | down to 3.3V | 8/16 | DIP, SO | current limited, DIP package no longer in production, autotest, electrostatic protection |
| TPIC2810 | 3-5V | 8 | SO | Uses I2C |
| MM5450 | 5-11V | 35! | DIP, PLCC | Way too many pins. |
| TLC5940 | 3-5V | 16 | DIP-28!, RHB, PWP | Onboard PWM, EEPROM-backed channel correction. Overfeatured. |
| PCA9635 | 2.3-5.5V | 16 | TSSOP | Onboard PWM, another overfeatured chip. |
| TLC5916 | no data | |||
| TLC5905PAP | 4.5-5.5V | 16 | PLCC-64 | Overfeature overdrive |
| UCN5833 | 5V | 32 | DIP-40, PLCC | Too many pins |
| ✓A6278/9 | 3-5V | 8/16 | DIP, SOIC | current limited, 25MHz data rate |
Whole-grid drivers[edit]
| Chip | VDD | Grid | Packages | Eval |
|---|---|---|---|---|
| max6952, 6953 | 2.7-5.5V | 20x7 | SSOP, DIP-40 | Includes onboard font, too specific? |
| max6957 | 2.7-5.5V | varies (20pin) | DIP-28 | Very configurable |
| MAX7219, 7221 | 4-5.5 | 8x8 | DIP-24, SO | SPI, current controlled, 800Hz |
