ULN2003和ULN2004有哪些區(qū)別？

The ULN2003A and ULQ2003A have a 2.7-kΩ

series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. TheULN2004A and ULQ2004A have a 10.5-kΩ series base resistor to allow operation directly from CMOS devices

that use supply voltages of 6 V to 15 V. The required input current of the ULN/ULQ2004A is below that of the

ULN/ULQ2003A, and the required voltage is less than that required by the ULN2002A.
