TC7MET541AFK

TC7MET540,541AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MET540AFK,TC7MET541AFK Octal Bus Buffer TC7MET540AFK Inverted, 3-State Outputs TC7MET541AFK Non-Inverted, 3-State Outputs The TC7MET540AFK and 541AFK 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 TC7MET540AFK is an inverting type and, the TC7MET541AFK is a non-inverting type. When either G1 or G2 are high , the terminal outputs are in the high-impedance state. Weight: 0.03 g (typ.) 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: VCC = 0 V Features • • • • • • • High speed: tpd = 5.4 ns (typ.) (VCC = 5 V) Low power dissipation: ICC = 4 μA (max) (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 = 1.5 V (max) Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 540/541 type. 1 2007-10-19 TC7MET540,541AFK Pin Assignment (top view) TC7MET540AFK G1 A1 A2 A3 A4 A5 A6 A7 A8 1 2 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 VCC G1 A1 A2 A3 A4 A5 A6 A7 A8 1 2 3 4 5 6 7 8 9 TC7MET541AFK 20 19 18 17 16 15 14 13 12 11 VCC G2 Y1 Y2 Y3 Y4 G2 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Y5 Y6 Y7 GND 10 Y8 GND 10 IEC Logic Symbol TC7MET540AFK G1 G2 TC7MET541AFK G1 G2 (1) (19) & EN (1) (19) & EN A1 A2 A3 A4 A5 A6 A7 A8 (2) (3) (4) (5) (6) (7) (8) (9) (18) (17) (16) (15) (14) (13) (12) (11) Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 A1 A2 A3 A4 A5 A6 A7 A8 (2) (3) (4) (5) (6) (7) (8) (9) (18) (17) (16) (15) (14) (13) (12) (11) Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Truth Table Inputs Outputs An X X H L Yn Z Z H L G1 H X L L G2 X H L L Yn Z Z L H X: Don’t care Z: High impedance Yn: TC7MET541AFK Y n : TC7MET540AFK 2 2007-10-19 TC7MET540,541AFK Absolute Maximum Ratings (Note 1) Characteristics Supply voltage range DC input voltage DC output voltage Input diode current Output diode current DC output current DC VCC/ground current Power dissipation Storage temperature Symbol VCC VIN VOUT IIK IOK IOUT ICC PD Tstg Rating −0.5~7.0 −0.5~7.0 −0.5~7.0 Unit V V (Note 2) V mA (Note 4) mA mA mA mW °C −0.5~VCC + 0.5 (Note 3) −20 ±20 ±25 ±75 180 −65~150 Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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).
