Description and Introduction

74HC/HCT573; Octal D-type transparent latch; 3-state The 74HCT573D is a high-speed Si-gate CMOS device manufactured by NXP Semiconductors. It is an octal D-type transparent latch with 3-state outputs. Key specifications include:

- **Supply Voltage Range (VCC):** 4.5V to 5.5V
- **Input Voltage Range (VI):** 0V to VCC
- **Output Voltage Range (VO):** 0V to VCC
- **Operating Temperature Range:** -40°C to +125°C
- **High Noise Immunity:** Typical CMOS levels
- **Low Power Dissipation:** 0.08mW (typ) per latch
- **Output Drive Capability:** 15 LSTTL loads
- **Propagation Delay (tpd):** 14ns (typ) at VCC = 5V, CL = 15pF, TA = 25°C
- **Output Transition Time (tTHL, tTLH):** 6ns (typ) at VCC = 5V, CL = 15pF, TA = 25°C
- **Input Capacitance (CI):** 3.5pF (typ)
- **Package:** SO20 (DIP20)

The device is designed for use in bus-oriented applications and features a common 3-state output enable input (OE) and a common latch enable input (LE). When OE is high, the outputs are in the high-impedance state. When LE is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the levels set up at the D inputs.
