Octal D-type

SN74HC573APW


Description: These octal transparent D-type latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports,bidirectional bus drivers, and working registers.While the latch-enable (LE) input is high, the Q outputs respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interface or pull-up components.

Features
  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads
  • Low Power Consumption, 80-μA Max ICC
  • Typical tpd = 21 ns
  • +/-6-mA Output Drive at 5 V
  • Low Input Current of 1 μA Max
  • Bus-Structured Pinout
  • 20-pin TSSOP
