Key Features
- 8-channel transparent D-type latch with 3-state outputs enabling high-impedance bus isolation for data multiplexing
- Active-low enable control (ENABLE LOW) with broadside pinout compatible with standard 74373 bus driver layout
- HC/UH logic family with 50 pF load capacitance rating supporting fast, reliable data bus applications
- 20-pin ceramic CDIP package providing hermetic reliability for military and high-temperature environments
Applications
The 8512801RA is used in microprocessor bus interfaces, data bus buffering, and address latching circuits where 8-bit parallel data must be held and driven onto a shared 3-state bus. Its broadside 373-compatible pinout simplifies board layout when replacing or upgrading existing 74373-family designs in industrial controllers and legacy embedded systems. The ceramic CDIP package makes it suitable for military-grade, aerospace, and high-reliability electronics requiring long operational life in harsh conditions.

Frequently Asked Questions
What logic function does the 8512801RA perform?
The 8512801RA is an 8-channel transparent D-type latch with 3-state outputs. When the enable input is asserted (active-low), the outputs follow the data inputs transparently. When enable is deasserted, the last data state is latched and held. The 3-state outputs allow the device to be placed in high-impedance mode for shared bus architectures.
Is the 8512801RA compatible with the 74373 latch?
Yes, the 8512801RA is described as a broadside version of the 373, meaning it is functionally and pin-compatible with the standard 74HC373 or 74LS373 octal transparent latch family. This makes it a direct replacement or upgrade in existing designs without requiring PCB layout changes.
What package does the 8512801RA use?
The 8512801RA is housed in a 20-pin CDIP (Ceramic Dual In-Line Package), identified by JESD-30 code R-GDIP-T20. Ceramic packaging provides hermetic sealing and superior temperature stability, making this device well-suited for military, aerospace, and high-reliability industrial applications.
What logic family does the 8512801RA belong to?
The 8512801RA belongs to the HC/UH logic family, which combines high-speed CMOS technology with low power consumption. The HC/UH family is compatible with CMOS voltage levels and typically operates from a 2V to 6V supply range, offering excellent noise immunity and drive capability for bus interfaces.
What are typical applications for the 8512801RA?
Typical applications include microprocessor address and data bus latching, memory interface address hold circuits, I/O port data buffering, and 3-state bus driving in industrial PLCs and embedded controllers. Its 8-channel parallel architecture and tri-state outputs make it ideal for any design requiring simultaneous latching and bus isolation of multi-bit data.
