The 150 MHz maximum clock frequency and 6.8 ns propagation delay at 5 V, 50 pF define the timing budget. The 32 mA source / 64 mA sink output drive handles heavily loaded data buses without external buffers, but the 7 pF input capacitance per channel adds up on a wide bus — account for it in the clock-tree fan-out calculation. ## Package and footprint — 20-SSOP specifics Housed in a 20-SSOP (5.30 mm body width, 0.209 inch pitch), surface-mount only. The supplier device package is the same 20-SSOP — no alternate package variant in this order code. The Tape & Reel (TR) and Cut Tape (CT) options are shipping formats, not package variants; the physical device is identical. ## Lifecycle and sourcing — active, no LTB pressure Listed as Active with RoHS3 compliance. No NRND or last-time-buy flags in the record, so this part can be designed into new BOMs without near-term obsolescence risk. The 74ABT family has broad distribution coverage; the SN74ABT273DBR is a standard catalog item.","metaTitle":"SN74ABT273DBR 74ABT D-Type Flip-Flop, 150 MHz, 20-SSOP","metaDescription":"SN74ABT273DBR 8-bit D-type flip-flop with master reset, 150 MHz clock, 6.8 ns prop delay at 5V.
