1 / 6 page SN54AHCT174, SN74AHCT174 HEX D-TYPE FLIP-FLOPS WITH CLEAR SCLS419E – JUNE 1998 – REVISED JANUARY 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D EPIC™ (Enhanced-Performance Implanted CMOS) Process D Inputs Are TTL-Voltage Compatible D Contain Six Flip-Flops With Single-Rail Outputs D Applications Include: – Buffer/Storage Registers – Shift Registers – Pattern Generators D Latch-Up Performance Exceeds 250 mA Per JESD 17 D ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) D Package Options Include Plastic Small-Outline (D), Shrink Small-Outline (DB), Thin Very Small-Outline (DGV), Thin Shrink Small-Outline (PW), and Ceramic Flat (W) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) DIPs description These monolithic positive-edge-triggered D-type flip-flops have a direct clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going edge of CLK. When CLK is at either the high or low level, the D input has no effect at the output. The SN54AHCT174 is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74AHCT174 is characterized for operation from –40 °C to 85°C.
