74VHCT540AFT,74VHCT541AFT CMOS Digital Integrated Circuits Silicon Monolithic 74VHCT540AFT,74VHCT541AFT 1. Functional Description • Octal Bus Buffer 74VHCT540AFT: INVERTED, 3-STATE OUTPUTS 74VHCT541AFT: NON-INVERTED, 3-STATE OUTPUTS 2. General The 74VHCT540AFT and 74VHCT541AFT are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHCT540AFT is an inverting type and, the 74VHCT541AFT is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the high-impedance state. The input voltage are compatible with TTL output voltage. These devices 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 3. Features (1) AEC-Q100 (Rev. H) (Note 1) (2) Wide operating temperature range: Topr = -40 to 125  (3) High speed: Propagation delay time = 5.4 ns (typ.) at VCC = 5.0 V (4) Quiescent supply current: ICC = 4.0 µA (max) at Ta = 25  (5) Compatible with TTL input: VIL = 0.8 V (max) VIH = 2.0 V (min) (6) Power down protection is provided on all inputs and outputs. (7) Balanced propagation delays: tPLH ≈ tPHL (8) Low noise: VOLP = 1.5 V (max) (9) Pin and function compatible with the 74 series (ACT/HCT/AHCT etc.) 540/541 type. Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales representative.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Output in OFF state. High (H) or Low (L) state. IOUT absolute maximum rating must be observed. VOUT < GND, VOUT > VCC 180 mW in the range of Ta = -40 to 85 .
