Key Features
- 16-bit bidirectional registered bus transceiver with independent control enabling flexible data flow management between two buses
- Select input supports multiplexed transmission of registered or real-time data, reducing external glue logic in complex backplane designs
- ACT-family logic with 75 mA output sink current and 50 pF rated load capacitance for driving backplane and card-edge buses
Applications
The 74ACT16652DLG4 is designed for high-drive backplane interfaces, memory bus buffering, and multi-card data exchange systems where bidirectional 16-bit data paths require registered latching. Its select input for multiplexed registered or real-time transmission makes it valuable in industrial VME/PCI bus bridge circuits and embedded processor address/data demultiplexing. The 56-pin SSOP package density suits space-constrained PCIe adapter cards, FPGA interface boards, and mid-range embedded computing platforms.

Frequently Asked Questions
What bus width and output drive capability does the 74ACT16652DLG4 offer for backplane interface designs?
The 74ACT16652DLG4 provides a 16-bit bidirectional bus interface with a maximum output low sink current of 75 mA per output. Rated at 50 pF load capacitance and housed in a 56-pin SSOP package, it can drive multi-drop backplane traces across processor and memory bus architectures without external buffer stages.
How does the select input on the 74ACT16652DLG4 reduce system complexity in a multiplexed bus design?
The select input allows the 74ACT16652DLG4 to switch between transmitting registered (latched) data and real-time (transparent) data on the same 16-bit bus without additional external multiplexers. This halves the chip count in address/data multiplexed bus designs by eliminating a separate selector IC, and the independent bidirectional control supports concurrent read and write arbitration.
For a new embedded computing board, when would the 74ACT16652DLG4 in SSOP-56 be preferred over a 74LVCH16652 in the same package?
The ACT family of the 74ACT16652DLG4 is optimized for 5 V bus levels and delivers higher output drive at 75 mA sink current compared with LVC-family equivalents typically rated at 32 mA. On legacy 5 V backplane bus systems or mixed 5 V/3.3 V processor boards where robust drive strength across 16 bits and 50 pF loads is required, the ACT variant is the preferred selection.
