This document introduces the IDT54/74FCT800 series of high-performance CMOS bus transceivers, including product features, functional characteristics and application scenarios.
The IDT54/74FCT861A/B and IDT54/74FCT863A/B are high‑performance CMOS bus transceivers designed for both commercial and military temperature ranges. They feature low input current, TTL‑compatible I/O levels, clamp diodes on inputs, and options for radiation‑tolerant versions.
The document lists detailed pin configurations, absolute maximum ratings, power‑supply characteristics, switching times, and ordering information. Key electrical parameters such as supply voltage, output drive current, and propagation delays are provided for both commercial and military versions.
| Commercial temperature range | 0 °C to +70 °C |
|---|---|
| Military temperature range | –55 °C to +125 °C |
| Output drive current per pin (IOL) | 48 mA (commercial) / 32 mA (military) |
Each output can source up to 48 mA in the commercial version and 32 mA in the military version.
Input capacitance is typically 6 pF, with a maximum of 10 pF at 0 V.
