| TC74VCX16600FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16600FT Low-Voltage 18-Bit Universal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs The TC74VCX16600FT is a high performance CMOS 18-bit universal bus transceiver. 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 in each direction is controlled by output-enable (OEAB and OEBA), latch-enable (LEAB and LEBA), and clock (CKAB and CKBA) inputs. The clock can be controlled by the clock-enable (CKENAB and CKENBA) inputs. Weight: 0.25 g (typ.) For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When LEAB is low, the A data is latched if CKAB is held at a high or low logic level. If LEAB is low, the A-bus data is stored in the latch/flip-flop on the high-to-low transition of CKAB. Data flow for B to A is similar to that of A to B but uses OEBA, LEBA, CKBA, and CKENBA. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge. Features (Note) * * Low-voltage operation: VCC = 1.8 to 3.6 V High-speed operation: tpd = 2.9 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 3.7 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 7.8 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 Bidirectional interface between 2.5 V and 3.3 V signals. 3.6-V tolerant function and power down-protection provided on all inputs and outputs Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down resistors. 1 2007-10-19 TC74VCX16600FT Pin Assignment (top view) OEAB 1 2 3 4 5 6 7 8 9 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 CKENAB LEAB A1 GND A2 A3 VCC A4 A5 CKAB B1 GND B2 B3 VCC B4 B5 B6 GND B7 B8 B9 B10 B11 B12 GND B13 B14 B15 VCC B16 B17 GND B18 CKBA CKENBA A6 10 GND 11 A7 12 A8 13 A9 14 A10 15 A11 16 A12 17 GND 18 A13 19 A14 20 A15 21 VCC 22 A16 23 A17 24 GND 25 A18 26 OEBA 27 LEBA 28 2 2007-10-19 TC74VCX16600FT Truth Table (A bus B bus) Inputs CKENAB X X X H OEAB H L L L LEAB X H H L CKAB X X X X A X L H X Outputs B Z L H B0 (Note 2) B0 (Note 2) L H B0 (Note 1) B0 (Note 1) H L L L L L L L L L L L X X L H H X L L L L X Note 1: Output level before the indicated steady-state input conditions were established, provided that CKBA was low or high before LEBA went low.

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).
