Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE74HC373 is an octal transparent D−type latch in a 20−lead DIP-type package. When the latch−enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the logic levels of the D inputs.

A buffered output−enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low) 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. Old data can be retained or new data can be entered while the outputs are in the high−impedance state.

To ensure the high−impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current−sinking capability of the driver.
  • Wide power supply range: 2V to 6V
  • Balanced propagation delay and transition times
  • Standard output drives up to 15 LS−TTL loads
  • Significant power reduction compared to LS−TTL logic ICs
  • Absolute maximum ratings*:
    VCC: −0.5 to +7.0V
  • IIK, IOK: ±20mA
  • Drain current (per output), IOUT: ±35mA
  • DC output source or sink current (per output), IOUT: ±25mA
  • DC VCC or GND current (per pin), ICC: ±50mA
  • Tstg: −65°C to +150°C
  • RthJA: 69°C/W
  • TL: +300°C
* Absolute Maximum Ratings are those values beyond which damage to the device may occur. Unless otherwise specified, all voltages are referenced to GND.
