8-bit D-type with 150 MHz clock ceiling
The Texas Instruments SN74ABT273N is an 8-bit D-type flip-flop from the 74ABT BiCMOS family, clocked at 150 MHz with a single positive edge trigger per element.
Supply, drive, and temperature envelope
Input capacitance is 7 pF typical, which keeps the clock-line loading manageable when fanning out to multiple devices on a shared bus.
Housed in a 20-pin PDIP (0.300" wide, 7.62 mm body) with through-hole mounting — the supplier device package is 20-PDIP, delivered in tube packaging. The DIP footprint is breadboard- and protoboard-friendly, and the 0.100-inch pitch matches standard perfboard layouts for quick prototyping or legacy board rework.
This is a standard-logic part from a mature BiCMOS family, so long-term availability through authorized and independent channels is typical for the 74ABT series.
