Device identity — TTL NAND gate
The Texas Instruments 54132DM is a TTL NAND gate, a fundamental logic building block for combinatorial functions in digital circuits. It is supplied in a Bulk package, which is the standard tube or tray format for through-hole or surface-mount devices, suitable for bench prototyping and low-to-medium volume production runs.
Note that this part is RoHS non-compliant — it contains lead (Pb) above the 0.1% threshold. This is typical of legacy TTL logic families and means it is exempt from RoHS restrictions for certain applications (e.g., aerospace, military, or industrial equipment with a RoHS exemption), but it cannot be used in new CE-marked consumer goods without an exemption claim.
Cross-reference and alternate sourcing
The JM38510/65103BCA is the closest drop-in equivalent for defense or high-reliability programs — it shares the same TTL NAND function and Bulk package format, but carries full MIL-STD-883 screening and a different ordering code. The SN74F30NS is a faster (F-series) alternative in a surface-mount SOIC package, requiring a board layout change.
