Frequently Asked Questions
What logic family does the SN74ABTH16260DLG4 belong to?
The SN74ABTH16260DLG4 belongs to the ABT (Advanced BiCMOS Technology) logic family from Texas Instruments. ABT devices combine BiCMOS outputs with CMOS inputs to provide high-speed switching performance with low input power consumption, making them suitable for high-performance bus applications requiring both speed and drive capability.
What is the data width and output configuration of the SN74ABTH16260DLG4?
The SN74ABTH16260DLG4 provides a 12-bit data path with multiplexed D-type latch architecture and 3-state outputs. The 3-state outputs allow the device to be disabled and effectively disconnected from the bus, preventing bus contention when multiple devices share the same data lines in a bus-oriented system architecture.
What is the output current capability of the SN74ABTH16260DLG4?
The SN74ABTH16260DLG4 can sink up to 64 mA of output current (I(ol) max), providing high drive strength suitable for driving large bus capacitances and multiple downstream logic inputs simultaneously. This high current capability makes it appropriate for backplane bus applications where long trace lengths and multiple receivers create significant capacitive loading.
How does the enable control work on the SN74ABTH16260DLG4?
The SN74ABTH16260DLG4 uses active-low enable control, meaning the outputs are enabled when the enable pin is driven low and disabled (high-impedance) when driven high. This control scheme is compatible with standard bus arbitration logic and allows the device to be easily controlled by open-collector or active-low control signals from bus masters.
What package and pin count does the SN74ABTH16260DLG4 use?
The SN74ABTH16260DLG4 is housed in a 56-pin SSOP (Shrink Small Outline Package) designated R-PDSO-G56. This package accommodates the high pin count needed for the 12-bit bidirectional bus exchanger while providing a compact SMT footprint suitable for high-density PCB designs in computing and communications equipment.
