TC74VCX16834FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16834FT Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs The TC74VCX16834FT is a high-performance CMOS 18-bit universal bus driver. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CK) input Weight: 0.25 g (typ.) is held at a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition of CK. When OE is high, the outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge. Features • Low-voltage operation: VCC = 1.8 to 3.6 V • High-speed operation: tpd = 3.3 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.2 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 8.4 ns (max) (VCC = 1.8 V) • Output current : IOH/IOL = ±24 mA (min) (VCC = 3.0 V) : IOH/IOL = ±18 mA (min) (VCC = 2.3 V) : IOH/IOL = ±6 mA (min) (VCC = 1.8 V) • Latch-up performance: −300 mA • ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V • Package: TSSOP • 3.6-V tolerant function and power down protection provided on all inputs and outputs 1 2007-10-19 TC74VCX16834FT Pin Assignment (top view) IEC Logic Symbol NC 1 56 GND NC 2 55 NC Y1 3 54 A1 GND 4 53 GND OE CK LE 27 30 28 EN1 2C3 C3 G2 Y1 Y2 Y2 5 52 A2 Y3 Y3 6 51 A3 Y5 VCC 7 50 Y6 VCC Y4 8 49 A4 Y5 9 48 A5 Y6 10 47 A6 GND 11 46 GND Y7 12 45 A7 Y8 13 44 A8 Y9 14 43 A9 Y10 15 42 A10 Y11 16 41 A11 Y12 17 40 A12 GND 18 39 GND Y13 19 38 A13 Y14 20 37 A14 Y15 21 36 A15 22 35 VCC Y16 23 34 A16 Y17 24 33 A17 GND 25 32 GND Y18 26 31 A18 OE 27 30 CK LE 28 29 GND VCC Y4 Y7 Y8 Y9 Y10 Y11 Y12 Y13 Y14 Y15 Y16 Y17 Y18 2 3 5 1 1 3D 54 52 6 51 8 49 9 48 10 12 47 13 44 14 15 43 42 16 41 17 40 19 20 38 37 21 36 23 34 24 33 26 31 45 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 2007-10-19 TC74VCX16834FT Truth Table Inputs Outputs Y OE LE CK A H X X X Z L L X L L L L X H H L H L L L H H H L H H X L H L X Y0 (Note) Y0 (Note) X: Don’t care Z: High impedance Note: Output level before the indicated steady-state input conditions were established, provided that CK was high or low before LE went high.

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).
