SN74ABT16374DL datasheet from Texas Instruments, 32.3 KB PDF, for a 16-bit edge-triggered D-type flip-flop with 3-state outputs, DL suffix indicating the SSOP package. The sheet should show pin assignments, the function table, setup and hold timing and DC characteristics. Technicians consult it when following latched data or address buses, checking clock and output enable inputs and identifying a dead bit or shorted output. Because the same logic comes in several packages, verify the pin count and outline before using these pin numbers.
