Part Description: Octal D-Type Flip Flop with 3-State Output

Part Details:

TC74VHCT374AF/AFT/AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT374AF,TC74VHCT374AFT,TC74VHCT374AFK Octal D-Type Flip Flop with 3-State Output The TC74VHCT374A is an advanced high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate TC74VHCT374AF C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state. The input voltage are compatible with TTL output voltage. TC74VHCT374AFT This device may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: Output in off-state TC74VHCT374AFK Features · High speed: fmax = 140 MHz (typ.) at VCC = 5 V · Low power dissipation: ICC = 4 A (max) at Ta = 25°C · Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min) · Power down protection is provided on all inputs and outputs. · Balanced propagation delays: tpLH - tpHL · Low noise: VOLP = 1.6 V (max) Weight · Pin and function compatible with the 74 series SOP20-P-300-1.27A : 0.22 g (typ.) (74AC/HC/F/ALS/LS etc.) 374 type. TSSOP20-P-0044-0.65A : 0.08 g (typ.) VSSOP20-P-0030-0.50 : 0.03 g (typ.) 1 2007-10-01 TC74VHCT374AF/AFT/AFK Pin Assignment IEC Logic Symbol (1) OE EN OE 1 20 VCC
