Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE74HCT573 is an octal D−type latch in a 20−Lead DIP-type package that uses advanced silicon−gate CMOS technology which provides the inherent benefits of low-power consumption and wide-power supply range, but are LS−TTL input and output characteristic and pin−out compatible. The 3−STATE outputs are capable of driving 15 LS−TTL loads. All inputs are protected from damage due to static discharge by internal diodes to VCC and GND.

When the NTE74HCT573 LATCH ENABLE input is HIGH, the Q outputs will follow the D inputs. When the LATCH ENABLE goes LOW, data at the D inputs will be retained at the outputs until LATCH ENABLE returns HIGH again. When a high logic level is applied to the OUTPUT CONTROL input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.

NTE74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices. These devices are also plug−in replacements to LS−TTL devices and can be used to reduce power consumption in existing designs.
  • TTL input characteristic compatible
  • Typical propagation delay: 18ns
  • Low input current: 1μA (max)
  • Low quiescent current: 80μA (max)
  • Compatible with bus−oriented systems
  • High output drive capability: 15 LS−TTL Loads
  • Absolute Maximum Ratings:*
    Supply voltage, VCC: −0.5 to +7.0V
  • VIN: −1.5 to VCC +1.5V
  • VOUT: −0.5 to VCC + 0.5V
  • IIK, IOK: ±20mA
  • IOUT: ±35mA
  • ICC: ±70mA
  • PD: 600mW
  • Tstg: −65° to +150°C
  • TL: +260°C
* Absolute Maximum Ratings are those values beyond which damage to the device may occur. Unless otherwise specified, all voltages are referenced to GND. Power Dissipation temperature derating: 12mW/°C from +65°C to +85°C.
