TC74VCXR162501FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXR162501FT Low-Voltage 18-Bit Universal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs The TC74VCXR162501FT 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 Weight: 0.25 g (typ.) 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 low-to-high 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-Ω series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge. Features (Note) • 26-Ω 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 TC74VCXR162501FT Pin Assignment (top view) IEC Logic Symbol OEAB OEAB 1 56 GND LEAB 2 55 CKAB A1 3 54 B1 GND 4 53 GND A2 5 52 B2 A3 6 51 B3 VCC 7 50 VCC A4 8 49 48 B5 A6 10 47 B6 GND 11 46 45 B7 A8 13 44 B8 A9 14 A10 15 43 42 B11 A12 17 40 B12 GND 18 39 GND A13 19 38 B13 A14 20 37 B14 A15 21 36 B15 VCC 22 35 VCC A16 23 34 B16 A17 24 33 B17 GND 25 32 GND A18 26 31 B18 27 30 CKBA LEBA 28 29 GND OEBA A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 B10 41 27 A2 B9 A11 16 OEBA CKBA LEBA A1 GND A7 12 CKAB LEAB 2 30 28 EN1 2C3 C3 G2 EN4 5C6 C6 G5 B4 9 A5 1 55 A16 A17 A18 2 3 5 3D 1 1 4 1 6D 54 52 6 51 8 49 9 48 10 12 47 13 44 14 15 16 42 45 43 41 17 19 40 20 21 37 38 36 23 34 24 33 26 31 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 B14 B15 B16 B17 B18 2007-10-19 TC74VCXR162501FT Truth Table (A bus → B bus) Inputs Outputs B OEAB LEAB CKAB A L X X X Z H H X L L H H X H H H L L L H L H H H L H X H L L X Note: B0 (Note) B0 (Note) Output level before the indicated steady-state input conditions were established, provided that CKAB was low or high before LEAB went low.
