Part Details:

TC74LCX16652AFT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX16652AFT Low-Voltage 16-Bit Bus Transceiver/Register with 5-V Tolerant Inputs and Outputs The TC74LCX16652AFT is a high-performance CMOS 16-bit bus transceiver/register. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This 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 device is bus transceiver with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the internal registers. All inputs are equipped with protection circuits against static discharge. Weight: 0.25 g (typ.) Features (Note) · Low-voltage operation: VCC = 2.0 to 3.6 V · High-speed operation: tpd = 6.0 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 levels fixed by means of pull-up or pull-down resistors. 1 2006-02-01 TC74LCX16652AFT Pin Assignment (top view) IEC Logic Symbol 56 1OEAB 1 56 OEBA 1 EN1 [BA] OEBA 1 1OEAB 1 EN2 [AB] 1CAB 2 55 1CBA 1CBA 55 C3 1SBA 54 G4 1SAB 3 54 1SBA 1CAB 2 C5
