This document contains device specific information
about the following devices:
• PIC16F73
• PIC16F74
• PIC16F76
• PIC16F77
PIC16F73/76 devices are available only in 28-pin pack-
ages, while PIC16F74/77 devices are available in
40-pin and 44-pin packages. All devices in the
PIC16F7X family share common architecture, with the
following differences:
• The PIC16F73 and PIC16F76 have one-half of
• The 28-pin devices have 3 I/O ports, while the
• The 28-pin devices have 11 interrupts, while the
• The 28-pin devices have 5 A/D input channels,
• The Parallel Slave Port is implemented only on

Additional information may be found in the PICmicro™
Mid-Range Reference Manual (DS33023), which may
be obtained from your local Microchip Sales Represen-
tative or downloaded from the Microchip website. The
Reference Manual should be considered a complemen-
tary document to this data sheet, and is highly recom-
mended reading for a better understanding of the device
architecture and operation of the peripheral modules.
