Detailed Product Description

1. General description

 

The 74HC245; 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).

 

The 74HC245; 74HCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HC245; 74HCT245 features an output enable input (OE) for easy cascading and a send/receive input (DIR) for direction control. OE controls the outputs so that the buses are effectively isolated.

 

The 74HC245; 74HCT245 is similar to the 74HC640; 74HCT640 but has true (non-inverting) outputs.

[1] CPD is used to determine the dynamic power dissipation (PD in µW):

PD = CPD × VCC2 × fi × N + ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

∑ (CL × VCC2 × fo) = sum of outputs.
