Part Description: Low-Voltage Octal Bus Transceiver/Register with 5-V Tolerant Inputs and Outputs

Part Details:

TC74LCX652FS TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX652FS Low-Voltage Octal Bus Transceiver/Register with 5-V Tolerant Inputs and Outputs The TC74LCX652FS is a high-performance CMOS octal 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: 0.14 g (typ.) Features · Low-voltage operation: VCC = 2.0 to 3.6 V · High-speed operation: tpd = 7.0 ns (max) (VCC = 3.0 to 3.6 V) · Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) · Latch-up performance: ±500 mA · Available in SSOP · Bidirectional interface between 5 V and 3.3 V signals · Power-down protection provided on all inputs and outputs · Pin and function compatible with the 74 series (74AC/F/ALS/LS etc.) 652 type Note 1: 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 2002-01-11 TC74LCX652FS Pin Assignment (top view) IEC Logic Symbol 21 OEBA EN1 [BA] 3 CAB 1 24 VCC OEAB EN2 [AB] SAB 2 23 CBA 23 CBA C4 22 OEAB 3 22 SBA SBA G5 1 CAB C6 2 A1
