Key Features
- 18-channel 3-state unidirectional bus buffer with dual independent active-low output enables for split-bus or half-bus isolation control
- ACT-family logic compatible with both TTL and CMOS input levels, delivering guaranteed output drive of 24 mA sink current per channel
- Compact 56-pin SSOP package enabling high channel-density bus interface in space-constrained PCB designs
Applications
The 74ACT16825DLG4 is used in high-density digital bus architectures, including backplane bus drivers, memory subsystem data path buffers, and address bus isolation in embedded computing boards. Its 18-bit wide, 3-state output structure makes it ideal for interfacing between processor buses and peripheral I/O expansion logic. The dual output enable inputs allow designers to selectively enable two independent 9-bit banks, providing fine-grained bus access control.
