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.

Features

  • Octal bidirectional bus interface
  • Non-inverting 3-state outputs
  • Multiple package options
  • Complies with JEDEC standard no. 7A
  • ESD protection:
    • HBM EIA/JESD22-A114-B exceeds 2000 V
    • MM EIA/JESD22-A115-A exceeds 200 V
  • Specified from -40 Cel to +85Cel and from -40 Cel to +125 Cel
