ÎÎ ÎÎ MC74HCT373A Octal 3-State Noninverting Transparent Latch with LSTTL-Compatible Inputs High−Performance Silicon−Gate CMOS http://onsemi.com The MC74HCT373A may be used as a level converter for interfacing TTL or NMOS outputs to High−Speed CMOS inputs. The HCT373A is identical in pinout to the LS373. The eight latches of the HCT373A are transparent D−type latches. While the Latch Enable is high the Q outputs follow the Data Inputs. When Latch Enable is taken low, data meeting the setup and hold times becomes latched. The Output Enable does not affect the state of the latch, but when Output Enable is high, all outputs are forced to the high−impedance state. Thus, data may be latched even when the outputs are not enabled. The HCT373A is identical in function to the HCT573A, which has the input pins on the opposite side of the package from the output pins. This device is similar in function to the HCT533A, which has inverting outputs.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. °C 260 Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. †Derating: SOIC Package: –7 mW/°C from 65° to 125°C TSSOP Package: −6.1 mW/°C from 65° to 125°C RECOMMENDED OPERATING CONDITIONS Symbol VCC Vin, Vout Parameter Min DC Supply Voltage (Referenced to GND) DC Input Voltage, Output Voltage (Referenced to GND) TA Operating Temperature, All Package Types tr, tf Input Rise and Fall Time (Figure 1) Max Unit 4.5 5.5 V 0 VCC V –55 +125 °C 0 500 ns Functional operation above the stresses listed in the Recommended Operating Ranges is not implied.
