IDT74FCT162373AT/CT/ET INDUSTRIAL TEMPERATURE RANGE FAST CMOS 16-BIT TRANSPARENT LATCH FAST CMOS 16-BIT IDT74FCT162373AT/CT/ET TRANSPARENT LATCH FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT162373T 16-bit transparent D-type latch is built using advanced High-speed, low-power CMOS replacement for ABT functions dual metal CMOS technology. This high-speed, low-power latch is ideal for Typical tSK(o) (Output Skew) < 250ps temporary storage of data. It can be used for implementing memory address Low input and output leakage 1 A (max.) latches, I/O ports, and bus drivers. The Output Enable and Latch Enable controls VCC = 5V 10% are organized to operate each device as two 8-bit latches, or one 16-bit latch. Balanced Output Drivers: 24mA Flow-through organization of signal pins simplifies layout. All inputs are designed Reduced system switching noise with hysteresis for improved noise margin. Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, The FCT162373T has balanced output drive with current limiting resistors. TA = 25C This offers low ground bounce, minimal undershoot, and controlled output fall Available in SSOP and TSSOP packages timesreducing the need for external series terminating resistors. The FCT162373T is a plug-in replacement for the FCT16373T and ABT16373 for on-board interface applications.
