Device package: 32 pin PLCC

Note: AD62 may also be used with windowed LCC devices by using a suitable packing shim. Contact sales office for details. AD50 is PLCC only.

Programmer socket: 28 pin DIL

Note: AD50 is especially useful for gang programmers, as it is less than 0.9" wide, to allow fitting to adjacent DIL socket positions.

Socket Specification:

Insertions: 5000

Replaceable: Yes

Fitted capacitors need not normally be modified but the following information is provided to assist our customers in special technical situations:

1. A location marked C2 is available to optionally fit a capacitor (eg 10nF) to bypass VPP supply (pin 2). This should not be fitted for devices which use this pin as an address line.

2. A capacitor (eg 10nF) is normally fitted to position C1 to bypass VCC supply.
