Toshiba 74LCX573FT 8bit-Bit Octal D Type Latch, Transparent D Type, CMOS, 20-Pin TSSOP

The 74LCX573FT is a high-performance CMOS octal D-type latch. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The 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 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE).When the OE input is high, the eight outputs are in a high-impedance state. All inputs are equipped with protection circuits against static discharge.

Low-voltage operation: VCC = 1.65 to 3.6 V
High-speed operation: tpd = 8.5 ns (max) (VCC = 3.0 to 3.6 V)
Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
Power-down protection provided on all inputs and outputs
Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 573 type
