- 20-pin Ceramic DIP (CDIP) package offers excellent reliability and hermeticity for military, aerospace, and high-reliability industrial applications
What is 8513001RA used for?
The 8513001RA is used as a data bus buffer in high-reliability digital systems including military electronics, aerospace computers, and industrial automation equipment where ceramic packaging is required for thermal and environmental robustness. Its 8-channel 3-state output structure enables shared bus architectures where multiple drivers must be gated on and off to avoid contention. The HCT family compatibility allows it to interface directly with legacy TTL logic and modern CMOS microprocessors in 5V systems.

Frequently Asked Questions
What logic family does the 8513001RA belong to and what are its input level requirements?
The 8513001RA belongs to the HCT (High-speed CMOS with TTL input levels) logic family. Its input thresholds are compatible with standard TTL logic (V_IL up to 0.8V, V_IH from 2.0V), making it a direct drop-in replacement for 74LS244 and similar TTL bus drivers in 5V systems.
What package does the 8513001RA use and why is it significant?
The 8513001RA is housed in a 20-pin Ceramic Dual In-Line Package (CDIP), JESD-30 code R-GDIP-T20. Ceramic packaging provides hermetic sealing, superior temperature cycling performance, and long-term reliability compared to plastic packages, making it the preferred choice for military, aerospace, and high-reliability industrial applications.
How does the 3-state output of the 8513001RA work?
The 8513001RA features an active-low output enable (OE) control. When OE is asserted low, all eight outputs are actively driven to their logic levels. When OE is deasserted high, all outputs enter a high-impedance (tri-state) mode, effectively disconnecting the driver from the bus and allowing other devices to control the bus lines.
What is the maximum load capacitance supported by the 8513001RA?
The 8513001RA is specified to drive loads up to 150pF per output channel. This higher capacitive drive specification compared to standard HC devices makes it suitable for heavily loaded bus lines in backplane and multi-board systems where long PCB traces and multiple device inputs accumulate significant capacitance.
Is the 8513001RA a non-inverting or inverting driver?
The 8513001RA is a non-inverting bus driver, meaning the logic state at each output matches the corresponding input when outputs are enabled. This simplifies system design by eliminating the need to compensate for signal polarity inversion in buffer chain calculations and bus protocol implementations.
