Texas Instruments SN74HCT573DBR Latch 74HCT573 D Type Transparent Tri State 59 ns 6 mA Ssop

The SN74HCT573DBR is an octal transparent D Latch with 3-state outputs. It is designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers. While the latch-enable input is high, the Q outputs respond to the data inputs. When LE is low, the outputs are latched to retain the data that was set up at the D inputs. A buffered OE input can be used to place the eight outputs in either a normal logic state 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. OE\ does not affect the internal operations of the latches.

• High-current 3-state outputs drive bus lines directly or up to 15 LSTTL loads
• 80?A Maximum low power consumption
• 21ns Typical tpd
• ?6mA Output drive at 5V
• 1?A Maximum low input current
• Inputs are TTL-voltage compatible
• Bus-structured pinout
• Green product and no Sb/Br
