Active 74ABT dual 8-bit flip-flop — 150 MHz clock, 4.7 ns propagation delay
The SN74ABT16374ADL is a dual 8-bit D-type flip-flop from Texas Instruments' 74ABT family, clocked at 150 MHz with a 4.7 ns max propagation delay at 5 V and 50 pF load — the delay sets the ceiling for daisy-chained register banks in a pipelined datapath; three or four stages in series consume 14–19 ns of the clock period before the data reaches the next combinatorial block. Outputs source 32 mA and sink 64 mA, enough to drive a 50-ohm backplane or a bank of LEDs without external buffers; the tri-state, non-inverted outputs let multiple devices share a bus line when the output-enable is gated per bank.
Quiescent current draws 2 mA, and input capacitance is 3.5 pF per input — the low capacitance keeps the clock-tree fan-out manageable for a 150 MHz clock sourced from a single oscillator driving multiple flip-flop banks.
48-BSSOP surface-mount package — board-fit and footprint
Supplied in tube (the standard 48-position tube), the part is also available in tape-and-reel for automated pick-and-place; the RoHS3-compliant finish means no lead-free reflow profile adjustment beyond the standard 260°C peak.
