Part Details:

TC74LCX16245AFT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX16245AFT Low-Voltage 16-Bit Bus Transceiver with 5-V Tolerant Inputs and Outputs The TC74LCX16245AFT is a high-performance CMOS 16-bit bus transceiver. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5-V supply environment for both inputs and outputs. This 16-bit bus transceiver is controlled by direction control (DIR) inputs and output enable (OE) inputs which are common to each byte. It can be used as two 8-bit transceiver or one 16-bit transceiver. The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable Weight: 0.25 g (typ.) the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge. Features (Note) · Low-voltage operation: VCC = 2.0 to 3.6 V · High-speed operation: tpd = 5.2 ns (max) (VCC = 3.0 to 3.6 V) · Ouput current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) · Latch-up performance: ±500 mA · Package: TSSOP (thin shrink small outline package) · Bidirectional interface between 5.0 V and 3.3 V signals · 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 2006-02-01 TC74LCX16245AFT Pin Assignment (top view) IEC Logic Symbol 48 OE 1 G3 1DIR 1 48 OE 1 1 1DIR 3 EN1 (BA) 1B1 2 47 1A1 3 EN2 (AB) 25 OE 2 G6 1B2 3 46 1A2 24 2DIR 6 EN4 (BA) 6 EN5 (AB)
