TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 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 is held at a high or low logic level. If LE is high, the A data is Weight: 0.25 g (typ.) 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 m A (min) (VCC = 3.0 V) : IOH/IOL = ±18 m A (min) (VCC = 2.3 V) : IOH/IOL = ±6 m A (min) (VCC = 1.8 V) - Latch-up performance: - 300 m A - 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 Start of mercial production 1998-08 2014-03-01 Pin Assignment (top view) NC 1 NC 2 Y1 3 GND 4 Y2 5 Y3 6 VCC 7 Y4 8 Y5 9 Y6 10 GND 11 Y7 12 Y8 13 Y9 14 Y10 15 Y11 16 Y12 17 GND 18 Y13 19 Y14 20 Y15 21 VCC 22 Y16 23 Y17 24 GND 25 Y18 26 OE 27 LE 28 56 GND 55 NC 54 A1 53 GND 52 A2 51 A3 50 VCC 49 A4 48 A5 47 A6 46 GND 45 A7 44 A8 43 A9 42 A10 41 A11 40 A12 39 GND 38 A13 37 A14 36 A15 35 VCC 34 A16 33 A17 32 GND 31 A18 30 CK 29 GND IEC Logic...
