Product Overview
This is one black plastic 14-pin DIP, its topside carrying the Harris logo, the character group I3-300-5, and a triangle followed by 8416. Harris let the logo stand in for the leading H on these parts, so the marking reads as HI3-300-5, the marking form of Harris ordering number HI3-0300-5, and 8416 reads as a 1984 week 16 date code. Harris's own 1982 cross-reference guide lists HI3-0300-5 as its second source for the Siliconix DG300CJ, a dual SPST normally-open CMOS analog switch in a 14-pin DIP.
Key Features
- Marking on this body: Harris logo, I3-300-5, triangle 8416
- Identifies as HI3-0300-5: HI3 prefix is the plastic DIP package, -5 is the commercial grade, per the Harris HI-series ordering grammar published on the sibling HI-303 datasheet
- Package: 14-pin plastic DIP, 0.300 in body width, through hole
- Function per the Harris 1982 cross-reference guide and the Siliconix DG300 datasheet: dual SPST, normally open, TTL-compatible CMOS analog switch
- Cross-referenced Siliconix DG300 figures: on-resistance under 50 ohms, turn-on in the low hundreds of nanoseconds; these are DG300 datasheet numbers, not Harris HI-300 numbers
- Pinout, absolute maximum ratings and supply limits for the HI-300 are not published on this page
- No Harris HI-300 datasheet is in circulation; work from the Siliconix DG300 datasheet and from the marking printed on this body before designing it in
Applications
- Drop-in bench stock for a board already carrying a Harris HI3-0300-5
- Repair of 1980s instrumentation and audio gear that used DG300-class analog switches
- Analog signal routing experiments on vintage-parts builds
- Reference sample for collectors of Harris-logo date-coded DIPs
Frequently Asked Questions
How many should I order? There is exactly one of these on the shelf and it is sold each, so the most you can order is one; if your repair needs a spare, the DG300 cross-reference is the number to shop under elsewhere. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Why does the body say I3-300-5 when you list it as HI3-0300-5? The H is the Harris logo printed to the left of the number, and Harris dropped the leading zero of the four-digit device number in topside marking, so I3-300-5 next to the logo is the shop-floor spelling of catalogue number HI3-0300-5. That reading is a strong inference from the marking and the published Harris ordering grammar rather than a mark that literally spells it out, which is why both spellings are on this page.
A part that spent forty-two years waiting for someone to notice the logo was doing double duty as a letter.
