Product Overview

The SN74HCT373N is an octal transparent D-type 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 LE input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. An OE\ input places 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. OE\ does not affect the internal operations of the latches.
  • High-current 3-state true outputs can drive up to 15 LSTTL loads
  • Typical tpd = 21ns
  • Inputs are TTL-voltage compatible
  • Full parallel access for loading
  • 80µA Maximum low power consumption
  • ±6mA Output drive at 5V
  • 1µA Maximum low input current
