TC74VCX16841FT

The TC74VCX16841FT is a high performance CMOS 20-bit D-TYPE LATCH. Designed for use in 1.8, 2.5 or 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation.It is also designed with over voltage tolerant inputs and outputs up to 3.6 V.The TC74VCX16841 FT can be used as two 10-bit latches or one 20-bit latch. The 20 latches are transparent D-type latches. The device has noninverting data (D) inputs and provides true data at its outputs. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch follow the D inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.

Features of the TC74VCX16841FT are:(1)low voltage operation:VCC=1.8--3.6 V;(2)high speed operation:tpd=3.0 ns (max) at VCC=3.0~3.6 V, tpd=3.4 ns (max) at VCC=2.3~2.7 V,tpd=6.8 ns (max) at VCC=1.8 V;(3)3.6 V tolerant inputs and outputs;(4)output current:Ioh/IOL=±24 mA (min) at VCC=3.0V,IOH/COL=±18mA (min) at VCC=2.3 V,IOH/COL=±6 mA (min) at VCC=1.8 V;(5)latch-up performance:±300 mA;(6)ESD performance:human body model>±2000V,machine model>±200V;(7)package:TSSOP (thin shrink small outline package);(8)bidirectional interface between 2.5 V and 3.3 V signals;(9)power down protection is provided on all inputs and outputs;(10)supports live insertion/withdrawal.

The absolute maximum ratings of the TC74VCX16841FT can be summarized as:(1)power supply voltages:-0.5 to +4.6 V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 4.6 V;(4)input diode current:-50mA;(5)power dissipation:400mW.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").Unintended Usage include atomic energy control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments,medical instruments, all types of safety devices, etc..
