| TC74VCXR162500FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXR162500FT Low-Voltage 18-Bit Universal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs The TC74VCXR162500FT 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. 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 Weight: 0.25 g (typ.) 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, and CKBA. 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. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge. Features (Note) * * * 26- series resistors on outputs Low-voltage operation: VCC = 1.8 to 3.6 V High-speed operation: tpd = 3.8 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.9 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.8 ns (max) (VCC = 1.8 V) * Output current: IOH/IOL = 12 mA (min) (VCC = 3.0 V) : IOH/IOL = 8 mA (min) (VCC = 2.3 V) : IOH/IOL = 4 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 TC74VCXR162500FT Pin Assignment (top view) IEC Logic Symbol 1 55 2 27 30 28 OEAB LEAB A1 GND A2 A3 VCC A4 A5 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 GND CKAB OEAB EN1 2C3 C3 G2 EN4 5C6 C6 G5 CKAB LEAB OEBA CKBA LEBA 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 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 3 5 6 8 9 10 12 13 14 15 16 17 19 20 21 23 24 26 3D 4 1 1 1 6D 54 52 51 49 48 47 45 44 43 42 41 40 38 37 36 34 33 31 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 B14 B15 B16 B17 B18 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 GND 2 2007-10-19 TC74VCXR162500FT Truth Table (A bus B bus) Inputs OEAB L H H H H H LEAB X H H L L L H CKAB X X X A X L H L H X Outputs B Z L H L H B0 (Note) B0 (Note) H L L X Note: Output level before the indicated steady-state input conditions were established, provided that CKAB was low or high before LEAB went low.
