Rochester Electronics, LLC 74167N

A decade rate multiplier produces an output pulse rate set by a four-bit BCD rate selection relative to its clock. The TI SN74167 family reference describes synchronous operation and facilities for cascading. The unprefixed 74167N catalog identity should be reconciled with the supplied device's markings and lot documentation before applying TI family data to a design.

The N suffix in the TI SN74167N reference indicates a 16-pin plastic dual-inline package. The local product's package field is blank. A 16-DIP type is present in the local package register, but the exact 74167N lot's body width, lead finish and pin-one orientation need inspection. The local 16-DIP JPG is missing.

Assembly checks

• Confirm the lot marking and count sixteen leads.
• Match the controlled top-view drawing to the PCB footprint.
• Inspect lead condition and storage history before soldering.

Missing local artwork and lot-specific mechanical evidence block publication.

The original TI family describes four rate inputs, clock, enable, strobe, set-to-nine control and Y/Z outputs. These are functional signal groups, not a verified physical pin assignment for the Rochester lot. Obtain the matching 16-pin top-view and truth table before wiring or substitution.

Do not infer physical pin numbers from this page.

Values drawn from historical family documentation are not guaranteed specifications for the catalog lot.

No LCDChip alternate is linked or approved. Before replacement, compare the exact manufacturer suffix, 16-pin top view, clock and control polarity, Y/Z output behavior, cascade connections, propagation timing, supply range and temperature grade. A similarly numbered rate multiplier is not automatically pin-compatible.

The local catalog names Rochester Electronics LLC. Original Texas Instruments documentation identifies the SN74167 synchronous decade rate multiplier and a later TI logic guide marks this historical function discontinued. Neither document establishes the original maker or revision of the Rochester-supplied 74167N. Request traceability, actual markings and controlled device data.

Inspect Rochester traceability, original maker marking, date and lot codes, package dimensions, lead condition and storage history. The catalog's stock and price are separate fields. An indexed distributor listing shows different quantity pricing and zero available stock; obtain a dated exact-part authorized quotation before updating commercial data or releasing the page.

Keep this item in manual review. Verify the Rochester lot's original manufacturer, 16-pin package and controlled electrical data; restore the 16-DIP JPG; reconcile dated exact-part stock and quantity breaks; then repeat content, database and rendered-page checks. No release or drop-in substitution is approved.
