This article is a GameBoy MBC1 schematic presentation. To more effectively grasp this principle, the proposal combine text read schematics. The circuit is simple but effective. The GameBoy MBC1 An important component is the 74HC32. For your clearer understanding of this principle, let's briefly 74HC32 . The 74HC32 is identical in pinout to the LS32. The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.74HC32 features are:
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0? A
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance With the JEDEC Standard No. 7A Requirements
• ESD Performance: HBM? 2000 V; Machine Model? 200 V
• Chip Complexity: 48 FETs or 12 Equivalent Gates
• These are Pb-Free Devices
