TC74VCX16374FT

The TC74VCX16374FT is a high performance CMOS 16-bit D-TYPE FLIP FLOP. 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. This 16-bit D-type flip-flop is controlled by a clock input (CE) and a output enable input (OE) which are common to each byte. It can be used as two 8-bit latches or one 16-bit latch. When the OE input is high, the outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge.

The features of TC74VCX16374FT can be summarized as (1)low voltage operation: VCC = 1.8~3.6V; (2)high speed operation: tpd = 3.0ns (max.) at VCC = 3.0~3.6V/tpd = 3.9ns(max.) at VCC = 2.3V/tpd =6.0ns (max.) at VCC = 1.8V; (3)3.6 tolerant inputs and output; (4)output current: (IOH/IOL) = ±24 mA (min.) at VCC = 3.0V/(IOH/IOL) = ±18mA(min.) at VCC = 2.3V/(IOH/IOL) = ±6mA (min.) at VCC =1.8V; (5)latch-up performance: ±300mA; (6)ESD performance: human body model > ±2000V/machine model>±200V; (7)package: TSSOP (Thin shrink small outline package); (8)power down protection is provided on all inputs and outputs. (9)support live insertion/withdrawal (To ensure the high-impedance state during power up or power own, OE shoud be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.).

The absolute maximum ratings of TC74VCX16374FT are (1)VCC power supply voltage: -0.5~4.6V; (2)VIN DC input voltage: -0.5~4.6V; (3)VOUT DC output voltage(VCC = off-state/high or low state, IOUT absolute maximum rating must be observed): -0.5/-0.5~VCC + 0.5V; (4)IIK input diode current: -50mA; (5)IOK output diode current(VOUT < GND, VOUT > VCC): ±50mA; (6)IOUT DC output current: ±50mA; (7)PD power dissipation: 400mW; (8)ICC/IGND DC VCC/Ground Current: ±100mA; (9)Tstg storage temperature: -65~150°C.
